MinimOSD Micro - Overview and Demonstration (KV Team mods)
ฝัง
- เผยแพร่เมื่อ 2 เม.ย. 2015
- In this video we will take a quick look at the excellent new version of the MinimOSD board - the MinimOSD Micro. This is one of the latest versions of the board and not only includes the excellent KV Team mods but also is only 15mm square.
The KV Mods allow you to connect your flight battery, current sensor, RSSI inputs and others directly to the board without the need for resistor bridges or fussy soldering.
If you are interested in seeing more of this board (and its cousins) in actions connected to boards like the APM, Naze32 and Multiwii you can watch the MinimOSD series on my channel - • Introduction to MinimOSD

I swear, every single damn time I am looking for anything rc related, I always come across your videos, I love the videos Lee!
:D Love you too! :D
Awesome video, you do a great job!
Thumbs up and thanks for your efforts and for sharing.
Cheers, Bob
thanks again, and again, and again.. big thumbs up for all your work!!!
Thanks for the video.
I have the minim and it is awesome.
Now i must test this little thing, great! :)
Great video. Now I know what I did wrong with my OSD no voltage.
Must shoulder pins for battery one.
Will definitely get The Mini OSD

Csaba Demeter
Yea. That metric system will make you swear :)
Annnnd this is why everyone should just use the metric system. Imagine an error like this when manufacturing the boards. "Oh yeah make it 50cm by 50cm that's pretty small."
dunno if you guys cares but if you're stoned like me during the covid times then you can watch pretty much all of the new movies and series on instaflixxer. Have been watching with my gf for the last few weeks =)
@Case Kyle Yea, I have been using InstaFlixxer for since november myself :)
Thanks for the amazing video!
Another awesome video and this new Mini MinimOSD sure is tiny making is great for 250 size quads ect thanks Painless360
Excellent George!
Great. This tiny thing is awesome. For a 200 or a 250 perfect. Great video. Thanks for your knowledge
Thanks for the comment, I *love* this thing and the fact that I can pop the main battery voltage/video voltage/current/RSSI into it without some very fine soldering is fantastic.
I have been watching the KV Team Mods threads and this is such a great piece of technology for the price.
Best of luck fitting it to the 250 quad. That is an ideal platform..
Happy flying!
which wire do i plug the rssi wire into a FS-IA6B TX. same TX as the tgy-IA6B.
So now the only issue I have is what to do with the RSSI??? Going into my X4RFr Sky. Since there is an RSSI on this board do I still hook it up through PWM on my flight control board? Will the FTDI pins display the RSSI ... Or do I put them both up to the minim OSD
I am always immensely impressed with the clarity of your discussion, sharpness of your videos, and wonderful diagrams.
I am a newbie that has been lurking on/over many FPV sites as I acquire hardware to make the plunge myself.
My concern is that newer cameras and transmitters are now adopting 3-5v power requirements, while the specs for many of the OSD systems are for 12v systems or partial 12v and 5v to different components.
I fried the cable between my Mini OSD from HobbyKing and my Eachine tx/cam combo from BangGood, apparently because I wasn't careful separating the power supplies from the 5v Eachine systems from 7-12v main board of the Mini OSD.
Do you have experience running the MinimOSD micro completely on 5v systems? Are there issues?
Also can you recommend a video or diagram which illustrates the OSD data layout in detail as a screen capture?
Thanks. Please continue your outstanding contributions to this hobby!
Jim
can you use this osd board with a cc3d FC?
Sorry if I've missed it somewhere, but can this run all the standard minimOSD software such as minimosd-extra? Or is it only compatible with code written specifically for the micro OSD? Cheers.
Help!? have i fried the osd already?! - when i plugged it into the pc to change the display its always shown a rapid flashing green light, i wouldnt say its bright at all like the others. it came pre flashed so i could put in into the quad - but - and this is where it gets strange, when i power up the quad the osd dont come on and the TX does but when i disconnect it from the FC then reconnect it, the TX turns off and the OSD comes on with the same rapid flashing green light. Can any one help at all please?
Making excellent progress with APM 3.1 mini thanks to your great videos. I bought the Mavlink TX/RX but didn't realise it used the APM telemetry port. Is there a way to still connect my MinimOSD Micro into the APM as well.
Thanks for all your help.
With the micro osd how do you wire the camera ground if your video transmitter does not power the camera, both my tx and camera run on 12v, the transmitter has a spare ground cable and the camera has just positive ground and signal, when using with no osd i solder both positive and ground together from both tx and camera to supply voltage and join the signal wire from the camera to the transmitter. Advice would be appreciated.
+quadthing copter the ground isn't for power, it's for the reference for the signal. See our video on using 12v fpv systems with 5v boards for more information.
I'm using the Mini OSD and seeing video, but the horizon bar is garbled characters. I am also seeing "No Volts" when it should be reading my battery voltage properly...not sure what to check next. I went into the Hawk Eye options menu and didnt see much there
Font file needs updating and check what the voltage is set to displaying... Best of luck
How does it read your battery voltage, you didn't have bat1 or 2 connected I'm really confuse. Plan on using micro minim osd with naze32.
J Sanders You're right I didn't - you connect the battery voltages to it as per the diagram to see the on-board packs.If you are using a Cleanflight powered flight controller it gets even easier..Best of luck.
Hi does this board can be program with the naza like the older version does? Thanks
SkyOrc The firmware and process for this great little board (and the basic MinimOSD) is detailed in the MinimOSD playlist - th-cam.com/play/PLYsWjANuAm4qfxLkr_RLlSF3qh_AwLYIT.html
Hope it helps.
I have a question. Do i need to add the resistors to the bat1 pin to get it to read the voltage correctly? I set it up to where my battery is connected to bat1 and gnd, but on my osd, it shows 0v.
www.holybro.com/manual/Micro%20minimOSD%20Manual%20v1.0.pdf
Wondering on how to setup up this MinimOSD Micro to a Naze32 and also using a Matek Mini Power Hub PCB V3.1 board. You say to connect the VTX and VRX cable to the Naze32 but on the Matek PCB there is also a place for these connection, so which one would be used or does it really matter?
Thanks in advance.
Check out the wiring diagram on this page - www.banggood.com/Matek-Mini-Power-Hub-Power-Distribution-Board-With-BEC-5V-And-12V-For-FPV-Multicopter-p-1005549.html ;) should help!
Great video once again, thanks.
One thing that is still not clear to me is the MinimOSD common grounds.
1. The 12v video in\out grounds are connected to the MinimOSD, Wouldn't it be better to by pass the MinimOSD ground similar to 12v plus red wire ?
2. The 12v VBAT ground is connected to the MinimOSD, Wouldn't it be better to connect only the 12v plus red wire directly from the battery ? ( as suggested in one of the Naze32 related videos in regards to FC VBAT pin )
Many Thanks Oren
Love your videos, always new things to learn. My question is I have a naze32 rev6, using INAV, for RSSI do I use the pinout on naze to micro minim in? To show it in OSD? Not been able to find these types of simple questions answered so have to ask. thanks again for videos
RSSI can be more complex than you first think as there are a few ways to send the RSSI signal to a flight controller or OSD. You need to know how the Rx you're using sends it as things like the MinimOSD like a voltage level rather than a PWM value.. Best of luck!
I am trying to avoid a ground loop. Are the Video in/out GNDs on the OSD connected to the main minimOSD ground that is part of the FTDI row of pins? I am wondering if it would be possible to connect the OSD only on the video line between the Tx and camera, without connecting the GNDs of the video pins. Then the camera and transmitter will have the same ground (from the TX in my case) and the micro minimOSD will have the ground from the flight controller. Not sure if this will work but it will definitely not work if the Video GNDs on the OSD are isolated.
+vzachari It works the way we've wired it here, you can try a different approach but I've never had any humming from a 'ground loop' on my models. Best of luck..
Hi Lee
I have one of these and I'm trying to use it with a APM board. I've soldered the pins on for the FTDI adpator and it powers up OK but I think its need another bootloader installing for Mavlink. Googled a lot but not much about loading the mavlink firmware on. The normal OSDConfig for minumOSD-extra just doesn't work and says try using Arduino IDE to put the bootloader. Wondered if you have any idea's. Or would I be better just getting the bigger board again. I had a couple and not lasted very long, one was my own fault. So I thought I'd try the mirco version
Thanks
Keith
The firmware should load fine using the FTDI. There are some non FTDI chipped adapters that don't work well. We use FTDI Basic adapters here.. Best of luck!
Would we need any LC filter or BEC like mentioned on some forums? Or sticking to the diagram would do?
+Joe Hannouch It works great here but I am aware that others have not been as lucky. Best of luck!
hi can you use ARDUINO 1.6.5 as that's the latest now or do we need to us 1.3 still ? think i'm going to put angle pins underneath pointing inwards to save more to fit inside my Gravity 280 !
+Jeff deakin I have a video on the channel about this - I would use 1.0.5 myself. Best of luck!
What's a good current sensor with at least 80A range to use with this OSD? So far the only one I have found is the TBS, but I don't like the T-Plugs that come with it.
+Kristian Leonardo Apuzzo Not sure - I'm not a user of current sensors here. You may be able to remove the connector and solder your favourite on. I've done that with a few pieces here. Best of luck.
Confused here..... I've set up the micro OSD but get nothing but VVVV characters on my video screen. I've not set up onto my naze board yet, just trying to make sure it works on the bench first. Any help would be great here
Usually because the fonts were not upload / didn't take after the firmware update. Check out the steps in the video. Best of luck!
Hi,
Can I power the micro minimosd directly from spare +-5V pins on naze32 or will it pull to much current?
Thanks
Bernard George You can, but make sure that the BEC you are using can handle the extra 500mA it needs.
Happy flying!
hello , can you help me connecting miniosd micro to flip32+ 10dof , flight controller , i cant find connection diagram for flip32+ , i need to solder some more pins on the flip32+ because , there are only esc pins and reciver pins not the serial pin , ive got an ftdi adapter if i need to flash another fw on minimosd micro
+neo36w eno36w I would use PPM for the Rx and that would leave the SoftSerial pins available for the OSD and then use them to connect to the MinimOSD. Program the OSD for 19,200 baud and set the SoftSerial port to the same speed. Best of luck.
I'm still trying to get this to work with my CC3D, I installed minoposd which communicates in UAVtalk instead of MAVlink. I can see a startup screen but that's about as far as I can get. scrolling through some of the minoposd threads it appears that the team KV mod is not supported because the board architecture is different.
mwalz135 CC3D and MinimOSD will be on the CC3D series coming soon..
Watch this space!
can this be run from the naze32 rev 6? just it say it need 500mv or do I need a bec ro run it.
Depends on how many amps the BECs can supply. You'll need 0.5amps for the OSD and about another 0.5-1A to run the flight controller and radio receiver... Best of luck!
i need some help i got the minim micro osd with a micro cc3d. it works fine but the voltage is wrong. I have a 3S Lipo 12V but the minim micro osd shows me 17V
+Frederic Refle watch some of the other MinimOSD videos or take a look at the forums or documentation for the firmware you are using. Many have adjustments for things like this.. Best of luck!
Have you noticed that the timer is off about 2 minutes after 6 minutes of flying? I had this problem with mwosd1.3 and had to reinstall 1.2. Any help on this would be appreciated. Thanks for all you videos.
I have not seen that myself but there are a few bugs coming to light in 1.3. You can read about them in the FPVLAB.com forum pages. I would pop post in there for the developers are work is underway to fix them.
Happy flying!
Is it possible to use this Micro MinimOSD board as a stand alone board? i was wanting to use it with the Atas mini PDB pro instead of the super simple OSD as the simple osd is not very accurate.
+MrP4LM3R I believe it is, but I've never used it this way. There are options in the MW-OSD 1.5 setup for GPS and other modes too. Best of luck with it.
looking to use this on my CC3D board, need to know if I can and what software I need to load onto it for best results. Thank you in advance for your help.
Yep, find the 'Introduction to CC3D' playlist and the video is in there..
I've got a zmr250 with naze32 rev6b and micro minimosd. My problem is that "low voltage" keeps blinking on my fpv screen. I'm using the VBat pins to the naze to monitor the 3s lipo. I've got the "use FC for battery" on osd checked. Voltage is correct on the screen and I have 3.5V per cell for alarm set on Naze. Why is the osd flashing low voltage on the screen?
You need to setup the low battery warning on the OSD - see our main MinimOSD videos for how you do that.. Best of luck!
Thanks again for another great video, sorry for all the questions as I'm new to Multiwii/Minim OSD, for main battery voltage (4S) do i just simple take a Positive/Negative from my PDB and wire this to Bat1 +ve/-ve on the board without the need for extra resistors as per your other video? KV Team Mod Board not micro, busy installing it just now but a little worried about putting 4S voltage straight to the board, also for RSSI I'm guessing I simply wire these from my RX (EzUHF) to the appropriate pins on the board then configure my rx for RSSi out in the ezUHF software,
Thanks again.
Rudeboys FPV Full specs here - www.rcgroups.com/forums/showthread.php?t=2325491
Up to 4s...
Painless360 Cheers, so i can just connect from PDB to OSD, good good, next just need to figure out the how everything needs configured in the GUI, no GPS just looking for basic info, RSSi and Battery monitoring, keep it simple to begin with, may add GPS at a later date, thanks again your videos have been a big help, I'm more used to EzOSD and Vector OSD, first time playing with Multiwii.
nice! thanks :)
Please help!! What type of "current sensor" will work with the minimosd? Can't find any info anywhere on this. I've got voltage but need something to read current. Love your vids:)
+Jared D sorry, we're not used one here and so many of the latest flight controllers have current sensing built in. A quick Google search found lots of information from others who have got it working. Best of luck!
The only thing i would add, is that people should install a switch to turn the tx or rx line from the naze minimosd "off" otherwise you wont be able to connect the Naze32 via USB, because the USB and RX/TX lines are shared.
i have a question about the mini OSD. Can the mini osd work without an apm? i want to use it on my fpv i have installed on my syma x8
You can set it up as a 'standalone' OSD but we've never tried here. Best of luck!
THX for your Videos, with out this, my MultiWii never Fly. Can you tell me, how i must conect the KV MOD Pins? It BAT1 my 12V Akku?, Witch port on the Reciver is for RSSI? and what is CURR? Excuse me, my english is from School, 30 year´s ago
See the videos we have on the MinimOSD. Google 'Painless360 MinimOSD' to find them. I've made quite a few working with the different flight controllers.. Best pf luck!
I got no picture on my screen and I don't know why.
When I connect my camera directly to the fpv transmitter they showing the picture.
But when I use micro minimosd there is nothing show on the screen like no signal.
Do you have any suggestion?
Thanks...
+Andri Rahmansyah Happy to help but please watch th-cam.com/video/olIqTiSJHIY/w-d-xo.html and come back to me with more detail of what you've tried..
Really helpful videos, many thanks. What FTDI adapter do I need, I checked Banggood but they seem to have a lot of them. Also what software download for APM Mini. 3.1.
Thanks
Derek
+Derek Northgreaves th-cam.com/video/qLaH4qkJNt0/w-d-xo.html and th-cam.com/video/Pxg5PEccumY/w-d-xo.html Lots od detail on the channel, the playlists help you find what you need if you can't using a normal search. Best of luck.
Hi Can you buy that video in/ video out cable anywhere, or do I have to make one.
I made mine to make it easy to pop between the camera and FPV transmitter. I used a few servo cables and modified them. Best of luck.
Can I use
MinimOSD Micro + GPS module without any flight controler?
Yes you can but it's poorly documented. Look at the 'Standalone' configuration for MinimOSD using things like KV_team software.. Best of luck!
ok i know that the osd level pitch line set for craft level...but is there a way to get the osd to let there be more then 15 degree of pitch...the pitch line stops moving about 15 degs.. i want to know what 45 degs. is when im in fpv..is there a way to do this??
+nitro 20 Depends on the firmware you are using in the OSD. Have a look at the pages for the documentation for it and see.. Best of luck..
+Painless360 I figured it out..now the pitch and roll degrees jump from 44 to 100..know anything on this.
Hello again, my other minimosd stopped working. I could only get the 2 light on but the blinking light doesn't come on, so I decided to buy this micro osd. After flashing and installing it on my Naze32, everything works well except for pictures. I could see all the OSD data on my screen but can't get any picture from my camera, but when I bypassed the OSD and connect directly to the transmitter, I get pictures. Could you please help on this? I have checked all my wires and everything looks good.
+Sol mag I would check the wiring and then also check the board settings in the firmware (PAL etc). Best of luck.
Hi ! Thanks for video.
I'm trying to setup my micro minimosd (MWOSD 1.6).
All data come from the Naze32 (Cleanflight) : Battery voltage and modes are working, but Throttle Position stuck at -90% and RSSI is not correct even after calibration. Any idea please ?
+Fosch sorry, no. I've not used v1.6. Id try a previous version. Best of luck!
+Painless360
Hey ! Just found a solution a half hour ago :)
I removed the following comments in Arduino by adding // :
// #define PWMTHROTTLE
//#define AUTOTHROTTLE (and I have entered my own min/max throttle values just below)
I'm still trying to make the RSSI working properly, problably the same kind of stuff...
+Fosch thanks for sharing that! Happy flying!
I'm waiting on your video on CC3D + MinimOSD Micro to finally put OSD in my quad. :D Do you know when you'll start the series?
Painless360 Bumping this comment, very very interested in what you come up with.
If i want to power the micro minimosd module with an external regulator, which wires should be removed?
I have 2 servos and when i control them the mmosd signal is lost, i also use apm2.5 and the voltage
regulator is a polulu 5V, 5A.
and if i have one bat. for frame and second for vtx, which one should i use for regulator?
because i burned a minimosd in the past when i was trying to use the same bat for both.
thx :]
+ssangry99 see how we did this on the APM 3.1 build in a wing. We powered the servos from a separate UBEC to keep the power to all the flight electronics clean to avoid problems like this. Best of luck!
so you cant configure the board unless u have an fti adapter?
Not that I've found..
hi been a while since i used my osd, and i have just dug it out its the first version you show on here ( without the voltage divider network ) which will be fine for what i want to do, but i was just wondering will i still be able to use the latest release mwosd version 1.6 on this old board ? have tried flashing it but i get an arduino error saying that low memory stability problems may occur... any thoughts on this please
+bing quadby what version of the Arduino compiler are you using? V1.0.5 is best..
yeah i have downgraded to an earlier version of arduino 1.6.2 always worked for me... dont know if you are aware, also there is a chrome version of mwosd....!!!!! now its much better than that clunky java version... uploaded latest mwosd and works fine not done the video in our connections yet but suspect it will work thanks painless.... running mwosd on inav
github.com/ShikOfTheRa/scarab-osd/releases/tag/v1.6.8.0 latest version with chrome configurator
so, if i want to see voltage status from my flight battery
i should solder my 4s battery wire directly to the grnd + bat1 without solder any resistor?
any limitation for battery voltage?
thx
+j3fron yes, not sure on battery limits, we've only used up to 4s here..
Painless360 ah thx for the explanation
before, i kept wondering if i should connect the minimosd from power module
but now its clear
thx anyway
5v connection shown at 6:55 in the video is backwards.
First of all I would like to thank you for your contribution to the community! I would like to know if I can add a GPS module like U-blox NEO-6M so to have that extra features as Direction to Home,Max Distance etc like the Tarot OSD TL300L has...Thanks in advance!
I have hard if versions of the code that allow for directly connected GPS but we've not tried it here. Best of luck!
Hi painless,
Thanks for the very helpfull videos.
I just installed the micro minim osd, and followed your video on the minim osd to configure cleanflight with the spracing f3.
When i power everything on, I get the menu at the start and the overlay, but "no data" and "disarmed" keeps flashing, as if cleanflight doesn't communicate with it ?? Have you encountered this issue ?
Thanks for the help
+Hamza Bendahou sounds like Cleanflight, the wiring to the OSD or the setup on the OSD is the problem. What troubleshooting have you done already?
Painless360 Thanks for your quick answer. I found the solution: I don't know if it is in the spracing f3 or in the micro minim osd but the tx and rx pins where inverted (not labled corretly). I suppose it is in the sp racing f3 since I was able to flash the micro osd using my ftdi adapter.
Sir I have connected everything but I am getting a low voltage warning on my googles.Can u tell me the problem?
Without more detail it's impossible to offer any advice. Happy to help but please watch th-cam.com/video/olIqTiSJHIY/w-d-xo.html and come back to me with more detail of what you've tried..
Hi this is great! Please can you tell us if it works with the CC3d (when you do the vid). Plus do you have a simple overview of what minimosd does and what clearflight is and now it works with LEDs? I saw some funky LED strips that indicate when turning and go red etc (Team-legit) and I am in complete confusion as to how it all fits together.
Zeebo Rutherford That's it. The MinimOSD videos are all in the MinimOSD playlist (detailed in the description) so you can fid the flight control board you are interested in (APM, Naze32, Multiwii etc).
Best of luck.
Painless360 Cleanflight LED video is here on the Naze32 playlist - th-cam.com/video/nt56WKJF5z0/w-d-xo.html
Happy flying!
are u sure about switching 5v and GND? (wrong diagramm)
Everybody else seems not to switch it and i cant find any other source confirming this
r3mixstyle There is a note on the video that you may not see if watching it on a mobile device. The graphic is wrong and the aux. +5v and GND are swapped.
Awsome vid..!! As usual.=) My question is, is it possible to feed RSSI off of pin 6 on the NAZE instaed of tapping of the DR4 pin 2sig... ? Thanks in advance.
Danks111 Not sure - I used the RSSI channel way of getting the values from the FrSky receiver into the Naze32..Best of luck with it.
ok thanks, ill try it and let you know how it goes.
Hello Painless,
at first, many many thanks for your Videos, its very helpful for me!
Question bout this osd, is this definitly working with an APM 2.5 and 2.8?
Thanks!
+Sven Koe It should do! Best of luck..
Excuse me do you know where can I get the FTDI adapter, in my screen I only see a Chinese simbols.
+Frank R. Pilot th-cam.com/video/qLaH4qkJNt0/w-d-xo.html ;) Search for 'FTDI Basic' on your preferred websites..
+Painless360 thanks I got it, and do you think whit that device can I remove the Chinese symbols y my screen?
No idea but you do need to upload the right firmware and fonts onto the board...
I need someone who can install firmware to a mini osd for use with cc3d mini revolution, help
Good Day.
I just received the Micro OSD as you suggested. It dd not come pre installed with software. Ok I went into Arduino 1.6.9 and verified the clear command. It verified just fine. went to upload the file to make sure I am strting off with a clean slate.

Any idea? I tried it with both of my new boards. I also bought 2 new FTDI boards like yours to be compatible.
I have tried several versions of Audrino from 1.3 to 1.6.9. Same error codes. Is it this hard to make these work??? I know yours was pre-installed but ......
Windows system does indeed find the FTDI board on COM5. I did set the software on com 5 , just fyi..
been on this 10 hours today. I am wondering if some other hardware on my computer is bad.
I also installed cp210 as well. When I hook it up to my quad I do see video and lots of V'S or down arrows over the entire screen!
so my rxtx and powers are correct as well as my vid in and vid out are good. have not got any further than that.
Please if you have any ideas or someone else that might be on spot with these Micro OSD's

I have a problem with minimosd micro. Some camera's don't give any osd display and my runcam skyplus does but wheb i use the horizon or other images, than they are messed up. Text is working withoud any problem. I did try other fonts but noting changed. Can it be de cam? wich cams do you use for your OSD? I wanted the HS1177 but they told me that also that one does not work with the OSD because of the chinese osd on it.
+emiel1976ep We use AOMWAY and FatShark cameras (with the odd Mobius and RUNCAM) here..
Thanks, i will try my runcam. The runcam skyplys gives some problems but now i now witch cam to get.
Any ideas of which current sensor would work well with this? Thanks and keep up the great videos.
Not sure, there is detail in the manual for the kv_team firmware.. Best of luck!
OK thanks for getting back with me, have a good day:-)
hi nice tutorial as always about the screen does it let you to move the reading where you like? like the minimosd?
That is a feature of the firmware you use. Read the readme files and release notes to see the options. Best of luck!
+Painless360 Does this firmware for osd is compatible with pixhawk?
Not sure - not used this board with the Pixhawk/APM MAVLink versions of the code.. Only one way to find out! Best of luck!
Hey there Painless, I've wired in my microminim OSD v2, I had no intention of using any of the functions other than displaying time and voltage, now i have "DISARMED/NO DATA" flashing on the feed, do you know how to disable this? I dont have the tx/rx pads connected.
That's because the board is expecting to see the data from the FC. To get rid of it I'd connect the TX/RX pins then remove all of the things on the screen you don't want using the GUI. Best of luck!
Found solution. in the flight controller section in config.h there is a //#define nocontroller. // out your actual FC and delete the // of the no controller line.
Nice find! Thanks for letting us know.. Happy flying!
Any chance you might do a setup/wiring video of the MinimOSD Micro as a stand-alone (without a flight controller) on a fixed wing? Maybe on a mini-wing such as the HK Bonsai? I think it would be a great application for FPV wing racing.
+Slappy McKracken I keep looking at this too. The documentation about GPS wiring and GPS config isn't great at all..
hello, can anyone say to me how i can connect minimosd micro with my vtx et200 (same as lt200) ?
Watch any of the MinimOSD videos on the channel - we cover it in all of them. Best of luck!
I've noticed on the MinimOSD Micro board there is a pad to connect a current monitor and was wondering if an APM Power Module would work with this board for monitoring current.
I would seem to that the APM Power Module would be ideal as it also provides a battery voltage monitor signal as well as a current monitor signal. With the newer Micro APM power distribution boards this is built in and would be ideal for a 250 quad build.
Question is can the current monitoring signal be used by anything else besides an APM/Pixhawk board? They are 'as cheap as chips' too.
BTW- Excellent TH-cam channel!! Thanks, and I really mean that!
James Lummel Not sure - I've not tried it. You will need to find the specification for the APM module and look at how that compares to the inputs on this board. Best of luck!
One more great description Painless, will it work with a Pixhawk?
It should do, see my videos about it in the Pixhawk series. Best of luck!
Greetings....
On your recommendations I picked up the Quanum Cyclops goggles and the Taranis Plus!. First they are just what I need to get started in fpv!
So now I am trying desperately to get the mini OSD configured (not Minum??). I see on the board it is the AT328P version. I downloaded all the files you recommended. Great. I am using the FTDI232 board to interface with the OSD. I have 2, 6 pin connectors to join them together. as yours had a female on it and just plugged it in. Now I have been on this for 8 hours but it seems that I can only get the arduino to recognize com 5. I thought I had an IRQ conflict on 3 so I changed it. Oh I am using Windows 10 on a laptop. I was able to clear the OSD with the clear command found in the KV Team folder that I created. it seemed to work but the lights never did turn amber. I then went to the next step to configure it with KV Team OSD.ino file I got this error code. I am not sure you have had this problem but here is the error code:
______________________________________________

Every other file I try to upload gives me a similar error 'item_table' ???
Do you or maybe some of your GURU's have any ideas??? I have tried this on 4 different boards. 2 were MavLink OSD which I will not use as I am using the NAZE32 Rev. 6 FC.
Any Ideas will be greatly appreciated as I am excited to use my new Cyclops Goggle!
DG
Try Arduino 1.0.5 not a later version.. Best of luck!
I have a slight problem. Installed mwosd on microminimosd and got everything working great. Suddenly I somehow deactivated the layout now only can see time. Is there a switch or something to make my layout come back, or do I have to reflash the board?
+Karstacus you can setup some firmware to change layouts using a switch on the transmitter. Check you haven't got that setup accidentally.. Best of luck!
+Painless360 Can I do this in the osd display? I have everything waterproofed. It happened right after a flight, so it must be something i deactivated by accident. Thanks.
+Karstacus in the configuration GUI on the PC..
+Painless360 Okay thanks :) Guess I have to take this apart :p
Da*n. I hate that when it happens.. Best of luck!
I had been flying using CC3D which I set up using your valuable videos.I would like to know how to install mini osd using the Naza m lite with GPS and using the fat shark teleporter v5.
Sadly we don't use any DJI technology on the channel so that's not something I can help with directly. This chap seems to be looking at what you're doing.. th-cam.com/video/k9r_Yu9U5rk/w-d-xo.html Best of luck!
Will this mirco minimosd works for CC3D? if yes which firmware to use. thanks
Ken C No, see the CC3D/MinimOSD video. It explains it all.
Thanks
+Painless360 Hi, thanks for excellent info :). I want to know is still micro minimosd not work with cc3d
I am huge fan fan of your videos; i recently buiilt a Quad based on your Naze32 videos. i am using Naze32 Rev 6, with GPS, SONAR, and Micro Minim OSD firmware R1.6. I checked all the cables, everything seemed to be OK. I was able to get the Video from the camera but no overlay. In other words, i am getting a Display 'DISARMED" all the time. Basically No Data from FC.
I have MSP enabled on UART1 with BAUDRATE of 115200 matching in the UI and the Sketch and UART2 is used for GPS connected to the 3 and 4th Pins on FC.
Also made sure TX-->RX and RX-->TX are connected between MinimOSD and the FC.
What am i missing? Any help would be appreciated.
If you're connecting the OSD to the TX and RX pins on UART1 then you'll only see data when the board is armed. Best of luck!
I am still not getting data after arming the board. i am still seeing "DISARMED" and "NO DATA" message.
All the steps we followed to get it working is in the MinimOSD/Naze32 video. I'd check everything again. Best of luck!
Hey painless360. I have been watching all your naze/flip videos and micro osd and i have 3 questions i hope you can shed some light on.
For the record im running cleanflight 1.9 w flip32+ on 3 quads now.
Q1: the micro osd w kvosd reeboots mid flight on one quad but not on my mini250. Any tips on why?
Q2: the volt info dont show up on the osd on this quad but it does on my mini250. Vbat is connected with a single wire on quad and both wires on mini250. Other than that they are the same. Cleanflight shows volt correcly on my computer.
Q3: on all quads the voltage displays the same as my multimeter in cleanflight sw on my pc. Iets say i have 12.4v. I set alarm to go off at 10.5 in sw and as soon as i take off the alarm keeps beeping. Why?
Keep the videos comming 👍😃
Solved q2. Had to activate use fc volt in gui.
Hope this helps -
Q1. I would swap the board over with a known good one and see. Could be a power problem on the quad or an issue with the board..
Q2. Yep, FC switch on voltage in GUI.
Q3. The voltage drops alarmingly (no pun intended ) when you pull a lot of power. Higher C packs cope better. I would lower the alarm again..
Best of luck...
Thank you! Will have a look at it tomorrow :)
Hi, thanks for you time. I have micro minimOSD working so pretty. But I like connect bluetooth module and see use same port how can I do?. B. Regards
+Camilo Reyes Have a look at the Naze32 series. Everything I know about the setups are in the videos. Sadly you can run out of pins on the Naze32 but if you're not bothered about LEDs then you can use Softserial to give you a few more ports to play with..Best of luck.
+Painless360 thanks for answer, and do you have any video to do that?.
We do look at soft serial in the telemetry video. Best of luck.
Will this MWOSD work with the APM board, and which parameters should I change to make it work. Nice channel, keep up the good work.
+LKbrilliant See the video on this very topic in the APM playlist..
+Painless360 I cannot flash the board, I was keep getting "programmer is not responding" error when flashing...
What troubleshooting have you done?
I bought another normal sized MinimOSD with a button on it, and flashed it.when first time it shown the "programmer is not responding" error on me again. I did again, this time, I pressed that button once the upload began, and it worked!
Great news! Well done. Happy flying!
hello can i use this with the pixhawk???
With the right firmware, yes. The process to set it up is the same as we used to connect a MinimOSD to an APM.. Best of luck!
FYI not sure if its just my micro minimosd or if MWOSD R1.6 changed it but my battery voltage is showing up in Video Voltage rather than Main Voltage. I am wired the same as your diagram. Not a big deal but took some time to figure it out thought i would share it with others.
+pMustangw on 1.6 use BAT2 for battery voltage. I had this same problem.
+Julich Mera Ahh Haaa i am glad to here its not just me. Thanks for speaking up
i have trouble with minim osd mikro. I have transmitter that requires 12v, and camera which requires 3.3v that why i use UBEC for camera. even if i connect tx and camera's GND each other, it doesnt work, picture is transmitting, but there is no OSD information..i think i have to find a 12v camera?
What troubleshooting have you done?
I couldnt test it with another camera yet. because i have only one. I tryed two different firmware which you shared with us at your channel. While it connected to pc, everything seems good. Im tryin to find 12v camera and will share results with you
+Baris Guler I would check that the fonts uploaded ok to the board. Not sure if this helps but this is a preview of a how to video covering 12v cameras - th-cam.com/video/bv-bsLjD2n0/w-d-xo.html
I wacthed the video, Im going to do some tests, Thank you to your quick reply and help. You are the man.
Hello,
Excuse me,I don't get it: why would I connect the APM's RX to any OSD's TX? What may the OSD send to the APM that should be relevant for the video transmission?
Sorry, I'm out of any idea...
Again, thanks for all your helpful vlogs...
Try it without that connection and see if it works.. best of luck
Thanks!
but..even if it does not give me any hint about "why", I have to report that i DID follw your directions, with both wires, and still, displays "No Data".. Any help available? I am going to check via 3DR, it used to work before...
Sounds like you have a far more basic issue than the intricacies of how the protocol works. If you do want to know why - then you can read up about the MAVlink protocol and look at its bi directional nature and handshaking.. best of luck..
yes, I figured the handshaking thing quite late!
Sir,
your "handshake" term gave me a lead, sth to think of ...
I probably should (and will !) be ashamed for asking next, but, actually, I was using the UART port from the FlightController (APM 252V5), to feed both the 3DR and this 'new' device of mine (the micro minimOSD).
They are wired parallel.
Since you evoked the 'handshake', which sounds to me as a synchro, I humbly asked about the necessity of having the RX from the OSD in use.
Now, would you say, my failure comes from this attempt of having both working simultaneously, thus, having two 'handshakes/hearbeats' that are conflicting?
This is all new to me.
I was naive enough to think I could fly and run the FPV+OSD on the one hand (the one eye!), and the run MissionPlanner with wireless telemetry (433Mhz) on the other.
Thanks for your kindness and patience!
Max
Could you please make a video on how to wire the MinimOSD Micro using the PDB with a LC filter rather then pulling power from the Vtx?
Not sure what you're asking...
Another words, most PDB have a 5V and 12V bec to supply filtered power to the video system. I was asking can you make a video on how to use the PDB to power the video system while incorporating the MinimOSD Micro. Thanks you.
I see! Thanks. We do cover this in one of the RC basics videos already and will be touching on it in the current build series
WARNING at 7:00 the pinouts on the right side +5v and ground are around the wrong way, should be ground at the top, cheers
Thanks for the comment. Missed that. I will add a note!
Painless360 the note needs correcting the "had" should be "has" good video thanks
the 5v is it to power the micro osd or is it to pwr the fc?
It powers both and the radio receiver too.. Happy flying!
I guess I mean the 5v on the osd or do I need to pwr the osd with my 5v bec that Already pwrs rx and fc
Power them all from the UBEC. You do need to have a UBEC that will supply 2A or more as the OSD pulls more current than you expect.. Best of luck!
if i dont connect to a flight control board will i still at least get a HUD?
You can configure it as standalone but need to add extra things. Check out the details in the Wiki.
+Painless360 i need a little coaching. i have minim osd with camera and video transmitter but all i get is NO MAV DATA? i dont want to connect to anything else, just want to see horiz line but i get nothing. can you coach me through please.
I've never done it but this video will explain the error you're getting (you searched the channel right?) th-cam.com/video/PTd5ViDsH1Q/w-d-xo.html
Best of luck.
Hello Painless360...thanks for all the tutorials that I followed to build from scratch my first quad...only one item left pending for my first dal 180 build :) which has become a nightmare now...how to get rssi from x8r into minim micro osd through flip32 (9xr pro with xjt module). It is the only thing I did not find from your "make it painless" videos :)
+Bruneau Melier Google 'Painless360 RSSI' ;)
+Painless360 unfortunately I do not have a tanaris but as stated, a 9xr pro with xjt module...
can we use this with apm?
+Ruteta Buraeke You should be able to but you need the right firmware on it. Best of luck..
Hello sir i have a weird issue with my micro minim osd, my fpv screen is filled with V's and F's and O's and what not. some values are flickering and those are in chinese.
Have really high hopes on you please solve it. I can mail you the pic. of it if you say .
Please Help please!!!!!!!!!!!!
I am using MWOSD 1.8 (purchased)
I am not able to find the solution anywhere.
That's usually because you've not uploaded the FONT file. See the setup videos for the MinimOSD in the Naze32 and SP3 series..
Want to add simple phrase to video. In my world that's about $99 USD. I'd like to use these at low cost- not for model. How could I use this to add simple 6 charter phrase ID to video signal outside of model? Do I need ardrino or PIC to generate ASSCI characters or other means? Don't have quad/ model circuit to help. Hopefully stand alone with minimal added items- looking for very low cost solution.
The MinimOSD is a great way to do that but the code we use in the hobby is designed to 'listen' to telemetry stream from the flight controller and then use that to put the characters on the screen. If you're familiar with Arduino then you should be able to rewrite the code to do what you want.. Best of luck!
Hello, great video, put i have a problem:with the the micro OSD on power (it works fine, latest firmware) I can not conect to cleanflight, i have to disconect the power to the micro OSD to conect to cleanflight, i also tested a external power to the micro OSD (ext. BEC voor testeing, same thing cleanflight does not conect onely after shot down power to the micro OSD, please can some one help!
+RC opter Not sure what you mean - videos showing the problem are always very helpful..
+Painless360
the cleanflight gaui wil not work if the osd is on power,
-osd power off and the cleanflight gaui is working wel.
I've left a message on that video - this is normal as the OSD uses the same circuitry as the USB connection. Happy flying!
I have a Micro MinimOSD, it came with Arducam OSD loaded. I was able to get video out of it but no telemetry. It would just display waiting for MAVlink heartbeats. At the moment I have disconnected everything and just have the FTDI connected.
When I power the board up through the FTDI the blue LED comes on and stays on, Geen LED flashes a few times then stays on. So I beleave it has a bootloader installed
I have now used Arduino and successfully cleared the EEPROM. I then tried to load KV_TEAM_OSD as per your videos. If I try to verify or upload I get the following error.

Any ideas
Thanks in advance for any help.
RC Lewis I would try it with an earlier version of the Arduino program.
Always works for me..
Best of luck.
+RC Lewis I had the same problem and I got the solution online. What I did was to change the line from "extern PROGMEM const char *item_table[];" to "extern PROGMEM const char *const item_table[]; and the error cleared. Hope this helps incase you haven't resolved it.
i cant access gui..says,, jave.w.exe... i think i got 1.5 flashed but i dont know..been at it for 5 hours HELP.
Sounds like something to do with your Java install. I'd install the latest version.. Best of luck!
+Painless360 yes it was..thanks again..
