FPV Tutorial: Setting up the MicroMinimOSD as a standalone OSD (no flight controller)
ฝัง
- เผยแพร่เมื่อ 2 มี.ค. 2017
- The MicroMinimOSD is a super cheap little device that works great in a Mini quad with a Naze-style flight controller, but is just as useful as a standalone OSD.
In part 1 of this video we'll look at exactly how you configure/flash the device to act as a simple voltage display/timer and then in part 2 we'll add in a GPS receiver to make a more fully featured OSD.
You can get some of the stuff I was using here (affiliate links use)

GREAT, I have searched many times for this information. Finally stumbled across your very informative video. Thank you much!
I'm sure to subscribe and follow your work. Iman old man with zero technical background so these types of videos are GOLD to me.
Again THANK!
Bit of an old video, but you can still make a basic OSD with it - so glad it was helpful
This is by far one of the best video's at least for a mac user to figure out. Thanks so much for the info a simple osd was all I needed and now I have it!!!!!!
Performed this install, following your video, into my FPV wing....and it works amazingly well. Super cheap solution to get my call sign, Vbatt and RSSI into my goggles. :) Thank you!!
Awesome video! Thanks for making it, super excited about the GPS setup next time round. Been thinking about a rembizi but it seems like I can achieve what i need (with a smaller form factor) for half the price. Thanks Wayne, have a nice weekend! :)
Just wanted to say thanks, this is exactly what I was lookin for. I tried a super simple osd, but it's bigger, cost more, and the voltage was off with no way to correct it. I've seen these tiny things for so cheap, but didn't know if they could work standalone. I was considering the cameras with osd, but don't wanna spend that much for all my fpv models, when they already have cams on them.
No problem. It's nice to know this still has some purpose. Now that flight controllers with inbuilt osd's and voltage displays in cameras have become the norm, the use of the MicroMinimOSD has sort of died off, but there's always a place :)
Very good video, thanks Wayne
Great Video. Well done. Learnt a lot. Thank you.
thank you so much for your hard work. Very informative video. I plan on putting this on my FPV racecar/rovers. I assume the gps you mention in video 2 would give me the car speed which would be pretty cool.
Yep - you could have car speed, distance from home and direction back to your home point. Seems like altitude would be a bit of a waste on a rover, but you can customize the OSD how you want it
Thank you, thank you, thank. It works with your help. Now I buy more of these, thanks again.
Great stuff - what are you using them for out of interest. With every flight controller having an OSD in these days, I was interested to know if it's still of use ?
@@CurryKitten I have learned a lot from it. It is a great video. Step by step for mwosd, editting in Arduino, and mwosd GUI. I use it fort two gliders, EasyStar and ElectroJunior. Both without FlightController. I will see the Voltage from the LIPO. With a little help from thermics long flights without risk. Thanks again.
FPV with gliders is great!
Nice - cool to see it those little OSD's have a role :)
To access the menu can this take sbus or ppm in stand alone mode ? Still watching, thanks
Hi Curry Kitten I have my osd and gps all setup and working great powering the minim and gps through a ubec and a cap for filtering everything else. All i have left to do is calibrate the Voltage and amps on the osd .I have read the minim has an osd menu that you can access with stick movements .Would i right in assuming i cannot do this with this configuration and i would need to be running through a flight controller to access the menu.
Yes when you wire to a flight controller to attach to a UART and have tx/rx pins to control things. How we've setup in this video is just a simple OSD-goes-on-top-of-video sort of thing. There's changes in the source you'd make as well so it would work on betaflight, for example, I used it years ago before OSD's being embedded in FCs was a thing.
Great instructional, this helps so much.
I guess Im kinda randomly asking but does anyone know of a good website to watch new series online ?
@Izaiah Jericho i would suggest flixzone. Just search on google for it :)
Hi Thanks for the video, really great. I have ordered OSd & GPS. The current vertion of the OSD is v1.7 . How do you set up for 1.7 as it is different from 1.6
The main difference is that there's a Chrome based configurator for it - which is paid for - but not too much. You can still go the 1.6 route if you want to do it all for free though.
Great video but I wish it included some info on how to calibrate rssi in this situation. Keep up the good work.

Please do a review on Eachine Falcon 120. I heard people say that it is better than the Eachine Wizard x220.
I've never heard people say that... where'd you hear this ?The 120 isn't on my radar as something I'd buy I'm afraid. I'm quite interested in a sub-100mm brushless quad and will build something at some point. If Banggood want to send me one to review, that I'll be happy to have a fly and review it, but I'll need at least another 15,000 subscribers until they start sending me any more review stuff
Thanks for the reply, on config file what do you comment as the OSD . Micto OSD? I still want to connec to the Ublock GPS
I think I cover this in the video at around the 5 min mark. You should uncomment WITESPYMICRO and have everything else commented out
Will this osd module display crosshairs?
Can the minimosd display artificial horizon as standalone? That's the main thing I need.
I don’t think so maybe if add some kinda of gyro add-on but otherwise I don’t think so. Too bad, it be nice if it did.
Im a bit confused Wayne....If I use the new MWOSD configurator APP, is that all I need..?....Or do I have to use the other software as well...?...Confused..?
You still need to do the few changes in the arduino IDE and then compile/write to the board. The new Chrome app is a replacement for the previous GUI to setup the actual OSD
Ah, thanks for that. It's not like Arduplane then where you can upload firmware and configure the OSD layout all inside the one package..?.....If not, why not..?..I assume in the old GUI....you can do it all..?...No wonder Im confused,..lol.
Nice Video Wayne....It will be more worthy once the GPS is on it for sure...Tempted to try MWOSD on my Minim too now.....Is it more reliable than Arduplane?
That I can't tell you - but I did have a minim on a copter based ardu, and I couldn't get it to work right at all. Just wouldn't request the right data from the ardu - so I'll have to go back and try it with mwosd. I tried a GPS on a walk around the park today. It works well. Complete OSD for £10 :)
Yes, Im interested to see how the GPS works out for sure. My Skylark Tiny is pretty good for the money and is small, but this looks like it will be even smaller. The GPS altitude will be pants of course, but the direction pointer accuracy will be interesting....My Skylark does not have the benefit of a compass either, but the basic GPS has saved my bacon more than once. Be interested to see it on a plane, at range, being used to the full extent during testing....I guess it might pay to use a good GPS puck also..?
I suppose the test is how usable is it using cheap and cheerful components. This will never go to a serious range - as I start to like using a decent AP for that - but I'll hope to get some decent test flights with it and see how it performs
Yes, I agree....I'd like to try it with my spare, full size cased Minim OSD....Watching this one with interest Wayne.
Thank you! Is this done just the same way on a Windows pc?
Yes - it's essentially the same - of course you'll see things appearing as COM ports in Windows
@@CurryKitten thx for fast reply. You explained so well, I have to give this a shot. I'm not into Betaflight so i figure this is the way to go.🤟
This is a good watch, CurryKitten. I am pretty clueless on how all this stuff works in the bigger picture, do I need an OSD? Does a Pixhawk Mini come with an OSD or those F4's? Am I free to pick and mount any OSD I like, or does it need to be compatible with the flight controller? Do I need to program ESC's (I read comments from racers talking about flashing them)? If my motors only draw 20A but my ESCs are 80A in total do they need calibration to work or will they work automatically? LOL as you can see, some of us are starting out from the buttomless pit of newbie skill levels and a bit info here and there like you are doing here is helping a lot :)
So many questions all at once :) ..and like many things the answer to them are usually "it depends" Exectly what are you wanting to fly/build to start with. Why do I ask ? Well the Pixhawk is a fairly full-featured autopilot, but it's not especially easy to config (many will disagree) and it's generally for your certain type of quad/plane - i/e a larger one where you might want to mess with automonous flight modes and have it RTH if you are feeling lazy. Does it comes with an OSD, no - it's the "usual" thing to use the minimOSD on the pixhawks which are very fussy about their voltages where you are flashing the font files over ! You can add standalone OSDs, and they will just grab infomation from their own GPS and based data on that, the idea of something like a minim is that it will talk to the flight controller and give you specific information (such as flight modes, way points etc) that a standalone one cannot. Do you need one ? Depends, what are you wanting to fly and what sort of flying do you want to do ?
You only need to worry in ESC terms if your motor is able to pull more than the ESC can support. So 20A motors coupled with 80A escs means that your ESCs won't break into a sweak, but you might be carrying more weight than you need (unless you mean that each motor is 20a and you have 80a ESC total... in which case is looks fairly well matched)
Calibration depends on what you are flying (again) and the type of ESC protocol that's being used. If you can fill in the details on what you are flying/intending to fly then I'll try and give a bit more info about what you might/might not need
Honestly, I did not expect you to answer those questions they were merely an indicator of where I am starting out. Thank you so much for your reply, now I know I didnt waste my money on parts I dont need :) But if you dont mind, yes I am building on a custom CF 500 mm frame with 2204 motors 1960kv Cobra's, 6040 props and 4 20A Hobbywing ESCs and a compact gimbal of sorts with either a Runcam Split or a Box camera. I am aiming for a DIY mavic-style quad with Lidars, payload dropper, searchlights on an extra motor connected to the gimbal controller and a trying to make a parachute work could be dead fun :) However, point-and-click is not my idea of a flying experience, I just need long flight times and safety like RTH because I am a newbie and that extra stuff is just for fun, probably too ambitious :)
Sounds like fun - nothing wrong with being ambitious :) Ok, so back in the day... and by day I mean around 2012 this size of quad was all the range, but one thing I'd mention is that we tended to use larger props at a lower KV. So the almost ubiqutous DJI f450 flamewheel quad used 2212 920kv motors spinning a 10" props (on 3s) and was a fairly good lifting platform. 6" props on a 500mm quad does seem a bit small, but I haven't tried to calculate lift on that kv/props so perhaps it's all good.
You might want to look at something like iNav on a standard flight controller for a cheaper way of getting some autopilot stuff. Get something like an Omnibus board and you have the OSD built in. You then just need to pair it with a GPS and then go through quite a lot of tutorials about how to set it all up.
As far as ESC protocols go, if your ESCs can run Dshot 600 then you'll get a smoother response and don't need to calibrate them. The Oneshot protocols are pretyt good still, but will need motor calibration. If your ESCs don't at least do oneshot125, then these days you should really consider changing them
please help me have a problem error compilling for board pro or promini ( exec: "c:\\ program filles (x86) \\ arduino\\ please? ser
DO you have the full error message, that one's just pointing to the arduino IDE location
Hello. Any idea on how to install it on Linux
That camera is a Firefly Q.... SSSIX!!!!
thanks
is possible to install this firmware at the conventional minimosd? I'm so boring with the actual screen from my osd with APM. The informations are big on my screen although I always set just battery, flight mode and time.
thanks for sharing man!
Yes it is ! I haven't done it myself yet... there's that slightly annoying thing that the minim can insist on having several types of power when flashing stuff... fonts at least IIRC. I think I needed both a 12v and 5v supply just to install a font without it corrupting ! (I think that was with ArduCam and I can't recall the OSD firmware I was running)
Trying this in 2020, the github page looks completely different. Can't find the right file to download
Same problem with me. On flashing in arduino keep failed. May be can info what version arduino is used as in video
Help! How do I get rssi on this??
There's an RSSI pin on the MicrominimOSD which you can set to analog voltage/PWM via a channel in the config software
@@CurryKitten wow you answered and so fast! Thanks so much I couldn't find this info anywhere! U got a new sub
I can’t get this to work.
I can't seem to get the configurator to work for me. It flashed ok, I got the 1.6 app up ok, I hit connect and lights flash and it says connected but I also have "waiting for OSD" and this never goes away, even if I try hitting restart, read, write or anything imgur.com/Du7HRp5
No way you could have reversed the TX/RX pins I take it (sorry to ask the obvious ones) Does it work ok in the old Java based configurator ? Does the OSD work ok outside of the configurator ?
I still have it plugged in to the FTDI in the way you showed. I couldn't find the old java based config - I would have preferred that TBH (got a link?) I haven't tried it yet Wayne - I assumed there would be nothing to see, but I can soon find out
Yeah - if you roll Github back to the previous release you can get it here github.com/ShikOfTheRa/scarab-osd/tree/v1.6/MW_OSD_GUI when you say - nothing to see, you have actually flashed the firmware on there I presume... else there will really be nothing to see
Just checked - I have a picture ok but no OSD at all - however, I have only a single signal in and signal out wire, and I noticed that you showed (V + and V-) in and (V+ and V-) out on part 1 - is this necessary? I use the same cam with a flight controller and that only needs signal in and out - I have only three wires on my Eachine cam - power + and - and signal
That's the version I downloaded Wayne - 1.6 (for windows 64 bit) - yes, it said it was successful, so I assume it worked, should I try again? - won't take a minute I suppose
At 4:45 seconds in you totally lost me! How did you get mwosd to show in Arduoino???
It's not. So the idea was here that I show where to download the MWOSD firmware, then showed where to download the Arduino IDE from, what I'm showing at 4:45 is what was contained within the zip file from the MWOSD download. That page is from finder, which is the Mac equivalent of explorer in windows - so just a file/directory browser.
CurryKitten on hooking up a gps do I connect tx to tx and rx to rx or do I do like normally osd RX to Tx gps and osd TX to Rx gps.
tx to rx - like on your OSD
I’m not using apple I’m on windows
your volume is way to low, increase please
No sats. Been sitting outside for 30min
In the other video (where I actually connect up the GPS) you'll notice it took me a while to actually find the right pins on the GPS receiver and I had to use an arduino to figure out what was what. Are you confident you have the right pins, do you have an arduino board so you could read the ASCII NMEA strings to confirm this ?
CurryKitten nope. I gave up. Moving on thanks anyway
youve lost me fair play...
Haha, sorry - it does seem complex if you are coming at this new. but if your aim is a basic voltage/timer OSD then it's not too bad to break it down into pieces. Let me know if you are getting stuck at a certain section
