Quite helpful in my project. Thank you for taking the time!
Thank you.
Very helpful tutorial. My raspberry pi 3 b's port broke and this really helps.
Thank you for your help Bob
I run a raspberry pie 3 b and have a mmdvm board attached on the pins so the info on tapping wires to the board was very useful many thanks
- Hi. Great to hear. Thanks for the positive feedback. Cheers.
What is the part called that connects to the GPIO pins and has the positive and negative wires (on the Raspberry Pi 3 in the video)? I am trying to find for my project.
can i ask would you be able you use a 10000mah battery for the pie 3 +
I will make a webcam from raspberry pi 3 A+ which in this project will occupy the PWR IN micro usb as the webcam communication input as well as power, because the power from the usb produces 500mA, it is certain that the board will not work optimally and does not have enough power to run the fan or oled display. My question is, will the board not be damaged if I connect an additional power supply of the same voltage through the two pads at 3:48 to increase the current?
thank you for the second option..
Thank you.
Great vidio man !!!
-Thanks.
I have some 18AWG solid core wire but don't want to solder directly under the micro USB so, GPIO pins it is. What female adapter do I need? What is the connector I need?
Nice video, what if the GPIO devices connected to the pi draws too much power, how can i power the PI and the other devices?
You should also explain about protecting power inputs when connecting directly on GPIO, since in RPi3B+ for example you're skipping the resettable fuse which is present on microUSB port.
Hi, i´m using a PC power supply to power a rpy 3b+ but show a yellow ray top left screen, the wire is thick enough, i suspects the micro usb connector. So, there is no other input point to power the board ?
Thanks
Hi , If I use the GPIO pins I lose the USB voltage protection, I think you mentioned this in response below. Do I lose that protection if I solder to the surface mount pads on the bottom of the board?
- Hi. I don't have a PI with me but all you need to do is follow the traces to see where those connections go. From memory, the pads at the bottom of the connector simply follow the same traces as the connector, so you would be going through the voltage protection circuit. If the traces or pads are different then see where they go and that will give you your answer for most PI models and other SBC's. Cheers.
Powering via GPIO bypasses the polyfuse in series with power connector +ve (Pi3 and up)
thank you for the video.
i'm new into this and i am wondering, if i would do the third option with the soldering, do i need software too on my raspberry? because i watched few videos about gpio on/off switch and there they always need some software.
when soldering how shown in your video can i only solder a on/off switch to the +\- cables and this should work then?
- Hi. Sorry I must have missed your post until now. If you want the software shutdown option you need a script (software) running on the Pi. This is better than just turning off the Pi. You can always skip the script and just solder the switch directly to the cable as you suggested and when you want to shutdown the Pi, shut it down through the operating system and then, when that is finished, turn off the power with the switch you soldered onto the power cable. This achieves the same thing as the shutdown script and GPIO connection. Cheers.
cool thank you for the answer!
Thanks for the information on Pi power please can you tell me the swg of the red and black cable thanks Bob
Use 24 or better. I was actually using 1mm solid core there, so 20swg.
Very useful thanks. That reduced the case size width for me
- Great to hear. Cheers.
3:50 It's difficult to tell what specifically he's pointing to.
I'm assuming its the two oval shaped grey spots closest to the edge of the board?
To be more specific about which ones I'm talking about, one is right above where it says PP5 and the other is right above where it says R3 ( from view perspective at 3:44 ).
Am I right in guessing those?
- Hi. If your talking about the two pads to which you can connect power, it is the 2 gold round pads directly beneath and on the opposite side to the micro USB socket. If you drew a rectangle on the bottom of the board around where the micro USB socket would be, the two pads in question would be in that rectangle. Hope that helps. Cheers.
My Electronics & Hacking Show cool, thanks man
It Will Help me a Lot..i want to make It USB charger..and plug on charger
that intro tho
Hello, I have couple of old mobile chargers (5v 1.8A and 5v 1.5A), usually my RPi without HDMI and USB devices does work with 5v 1.8A charger, So can I use other charger to provide power via GPIO pin? Is it possible to 2 chargers to power on same board?
TIA.
- Hi. Im not sure how the Pi will react since I haven't tried to do that before. My best guess is it will work as the power channel is the same regardless of the input, with the exception that power going in via the GPIO pins is not regulated. Cheers.
Great video, I like it very much. Did you know that the raspberry pi 1 could be powered through the usb port
+Tiny Plays - Thanks. Just a quick one I wanted to do. Now starting on the next project. Cheers.
+My Electronics & Hacking Show Cannot wait to see it. I have you on alerts so as soon as you upload I'll know
I discovered this when testing completely by accident
Brother I was facing a problem
I have a raspberry pi 3 b
The raspberry pi is giving a low power sign on top right corner of the screen I tried many mobile chargers 5v 3.1a but still having that low power sign can you help me with that?
Hi, is it possible to power Pi with both GPIO + also use microUSB as a backup power with power bank?
- Hi. Yes it is. Just make sure your voltage going to the GPIO is accurate (no over voltage). Cheers.
Hey check this thing out th-cam.com/video/gr8nxEfSeEA/w-d-xo.html its pretty cool
@@michaelsstuff4402 Hi, so it is possible to use a 2.1 A smartphone charger and an 1 A charger with pinout? Will none of those components get destroyed? I mean if the pi tries to draw more than these 2.1 Amps, the charger will get destroyed because it's an unsafe one coming from china with no safety mechanisms, which means it would burn...
ty in advance!
I have an Orange Pi One Plus, i seem to have a "dead" board or power supply issue. Is this video of use to me? It's never turned on from since i've ordered it.
Hi. I think so. Take a look at the video and then find a copy of the GPIO pinout for your board. If the USB power input is faulty but the rest of the board is okay, you might be able to power your Pi from the GPIO, just like you can with many other boards. Cheers.
Nice video. About Pi3, do you know if I can use the test pad as the the power input for the Pi itself ? PP1 is +5V and PP5 ground is that is that correct?
- Hi. You can use the pads on the bottom of the Pi for sure (as per the video). I can't remember which numbers they are but the two I identified in the video are the one to use. Just remember to keep the power clean. No 4.5v or 5.5v input. Sorry the answer is a bit vague. I don't have access to a pi right now. Cheers.
thinking of working on a project with a raspberry pi zero wireless, I was thinking of powering it up using the USB voltage on a tv, would this work.
- Hi. The Pi Zero W will draw 150ma at idle and is supposed to be powered by a 1.2A supply. Most tv's USB ports are 500ma rated so you might get the Pi Z to boot and do the minimum but you could run into reliability issues when pushed. Cheers.
im a little late, but i wanted to know how i could have both a pi and a 14"-15" screen powered with only one power input. Im not really looking to add a battery. Also how would i add a power button?? (clearly im a begginer)
edit: im probable going to use pi 3 b
- Hi. The answer is yes. Its easier if the LCD screen you use can be driven by a 5V source (some can), that way you just need a 5V supply with enough current for the Pi and the LCD (about 3.5A). If your LCD is a 12V unit then you will need a step up converter to get the 5V supply up to 12V. Alternatively you could use an external 12V source and use a 5v step down converter for the Pi but it will need to be able to handle at least 2.5A, preferably more. Cheers.
So, the issue that I have with using power supplies isn't so much the voltage but the amps. I can find a psu that gives the 3v, 5v and 12v is needed, but the amps are a mystery. How do I ensure that I get the 3A needed out of the psu?
It won't draw more than 2.5 amps at 5 volts. That's just the maximum current it will consume. You could hook it up to a 100 amp supply and it will only draw a maximum of 2.5 amps. Get a power supply that will supply 2.5amp and above and you'll be fine.
@@haydo8373 Thank you for that. It's been a mystery for a while.
Can you use the updated Raspberry pie 3 B+ for s stratux build?
- Hi. I've heard that there are some issues with STRATUX and the new Pi. Might be best to go with the 3b. Cheers.
What I'd like to know, is how long can I power a Raspberry Pi 3 using a 4000mah USB power bank? I know it depends a lot on the load, but I'm just referring to basic power consumption by the Pi with USB keyboard/mouse and HDMI display. Thanks
- Hi. Is the power bank powering the HDMI display as well? If not then average use will see a PI 3 draw a peak of 2.5A and a low of about 1A, so the average is about 1.75A. Your 4AH power bank might last 2 hours. Its worth noting that cheap power banks won't deliver 2.5A out of a USB port (usually less than 2 and the 5V supply often drops to 4.6V) and the Pi 3 at load will require 2.5A @ 5V to run perfectly. A higher quality power bank will be capable of a genuine 2.4A from 1 USB port and can hold the 5V output which is close enough to keep the PI3 happy. Cheers.
Or, just purchase a quality UPS (Uninterruptible Power Supply).
can i power rpi 3 from 5v 5A smps through power port (micro usb )?
TAPAN MOJIDRA - Hi. Yes you can. The Pi3 won't draw 5amps but you can certainly power it with a 5v 5a supply. More than enough power. Cheers.
My Electronics & Hacking Show sir how to convert hdmi to rca?
TAPAN MOJIDRA
- Hi. You don't need to as the Pi boards have composite out (RCA). On the Pi 3 its done through the 3.5mm TRRS connector. You just need a suitable cable to get 3 x RCA out. If you really need to convert HDMI to RCA you need a separate digital to analogue converter (DAC).
bro can i powerup my raspberry with 5v ,2 amp adapter
Curious, I had powered a raspberry pi 3 using gpio pins and It worked for about a week then seemingly fried the chip and I had to replace. I used a 120v to 5v step down
- Hi. Yeah the GPIO are a good option but your supply needs to be regulated and clean as the normal input protection you get through the micro USB port is bypassed when you power through the GPIO. Cheers.
My Electronics & Hacking Show what would you recommend doing to achieve that?
- Best bet is to use a quality 5V DC to DC voltage reg. There are lots of choices but it depends on the power supply you are using. I typically use Pololu U3V50F5 regulators which are boost regs when using lithium battery power supplies. If you are using a power brick which is dropping 120v AC to 5V dc then I would still use a 5V reg as the power brick is unlikely to be very clean. Hope that helps. cheers.
My Electronics & Hacking Show thanks!
amazing tutorial
i want to make It on powerbank,conect It directly to powerbank,but my question os: could It Be hybrid? i mean the (+) and (-) from rasp connected on powerbank and USB charger at same time,when unplugged It work with powerbank..when put directly energy It charge and uses pi Power directly
- Hi. Its possible but you would need to make sure the output (USB) from the powerbank can output enough power for your project. The Pi by itself needs 5v at 2.5amps. Most powerbanks only put out 2.1amps. I would suggest making your own that can output enough power. I will be doing a video soon about making a high powered powerbank. Cheers.
My Electronics & Hacking Show really? amazing!!!! i Will wait...my project dont need rush because i buyed raspi3 but It Will come only Next week...so i Will stay tuned! thank you
Hi. I've attached a Navio2 to a Raspberry Pi 3 Model B. The Navio2 powers the pi. I have a power module attached to the Navio. Plugged in a 3S LiPo Battery. When I plug in a wifi dongle there isn't any power to the USB wifi dongle. Is there a reason for this? The forums and the few videos I've looked at everyone just plugs in their wifi dongles and, hey presto!, it has power. What aren't I doing right? Some help please. :D
- Hi. I have looked at the Navio2 briefly. There could be a couple of issues. The Navio provides power to the Pi and the Navio also requires power. How much power are you supplying the Navio? It should be 5V at 3A. Second, the Navio takes over many of the pins on the Raspberry Pi. It is possible that the serial bus is taken over by the Navio meaning USB might be disabled. Lastly, you could have a faulty Wifi dongle. Disconnect the Navio, plug the power supply to the Pi and connect the Wifi dongle. If it works then its the Navio. Also, why not use the Wifi built into the Pi? Cheers.
I've tried the wifi dongle on my Desktop PC and that works fine. Can rule out a problem with the wifi dongle, i guess. The Navio's Power supply: Power module, servo rail, USB copy from the Emlid website about Naivo2. Average current consumption:
- Sounds to me like the dongle you have is not Pi compatible. All i can suggest is try another dongle that is known to work with the Pi. Cheers.
the model 3b+ requires 2.5A, what are the options to supply this to the system? USB cable from laptop is out of the question, so only option i see is the official power cable... boring
- Hi. The original Pi3 also needed a full 2.5A for happy operation. The official power supply actually pumped out 2.5A at 5.1V just to give that little bit more and compensate for the loss through the cable. The official cable also has thicker than normal wiring normally only found in the best USB cable. Having said that, you have many options for the Pi3B+. The only real trick is to use good thick wire (relatively) and a source that can give 2.5A at 5V. I have used many aftermarket plug packs (wall warts) and some of the power boards that have USB ports built in. To use those successfully you just need to source a good quality USB cable. If your chopping up a plug pack then just use good wire. Cheers.
Sorry about this but I had a question for a build I am considering doing. Is it possible to desolder the hdmi port and solder the hdmi wires where the hdmi port was
+Tiny Plays Yes you can, Ben Heck has done it but it is difficult because it has a small pitch,
I think you would be better off buying an HDMI connector male piece and put that in, you won't lose too much space and can use thinner wires that are more flexible.
+Glychee S Well I am trying to fit the pi into a 5 inch by 2.75 inch case
I have a PI3 and the connectors i was talking about, if i put the connector in it's 89 mm by 70 mm which is 3.5 inch by 2.756 inch, i don't know how accurate your measurement was but you could use the connector i talked about and shave off a bit,and it should work for your purposes
+Glychee S I did it by looking by the 5 inches was the correct measurement
the 5 inches are not the problem, the 2.75 inches are, with my connector on it's SLIGHTLY larger than that, but you could make the connector a bit shorter(use a file).
I have a picture here and an ebay link to buy the connectors if you're interested in my solution, it's your choice though,i wouldn't solder the fine hdmi pitch simply because i can't.

how i can connect 12V lipo battery to rasbi 3 ? i need 12 volt to display 10 inch rasbi display power, and 5 volt to rasbi 3 board, how this need do ? and need HDD connect to rassbi too.what hub i need ?
You need a Step Down voltage regulator. Look up UBEC on aliexpress or ubec or whatever for cheap, ok ones
Yeah cool vid but it didn't answer my question. I have 3 Pi's currently and will probably be getting two more. I really want to get rid of the official power supplies and just use USB cables. It would streamline the whole thing and look a lot neater. Can this be done? Does anyone make a powered USB hub that would work or would I have to put something together?
- Hi. Yes that would work. All you need to do is make sure the total power supply is enough for the 3 PI's at full load and make sure each PI is getting its fair share (2.4A). You can either use a single 7.5A or more 5V power supply or use a bigger supply and run 3 individual step down power regulators so each PI gets its own reg able to provide 5V at 2.4A. Most USB hubs will provide power through each port but most have a total power output less that what you need. Cheers.
So the upper limit for a micro usb port is 1.8A yet the rp3 needs 2.5A. Why do we still use micro usb for power again? If the rp4 is more powerful theyll have to come up with a more robust solution
- Hi. Yes the micro USB port is not the most maker friendly port to use either. I have taken the RPi 3 official power supply apart and I can tell you that the wire gauge they used is much thicker than typical wire you find in normal micro USB cables. But I get your point, how much power can we really push through micro USB connections. Cheers.
Can i power pi through usb ports on my pc? If i can isnt pc output 12v?
- Hi. No you can't unless your taking about the Pi zero, and even then you shouldn't. A PC USB port outputs 5V and usually at a max current of 0.5A. A Pi 3 needs 2.5A at 5V for full operation. You can sometimes boot a Pi with less current but not 0.5A from a USB port. Cheers.
So if you have a usb wall plug, you just plug it in an it turns on?
- Hi. If you mean just provide power from a USB wall socket to something like a Raspberry Pi then yes, that is all you need to do to power these types of boards. The only real consideration is the current being provided by the outlet. Many wall type outlets are rated at 2 amps. That is enough for a Raspberry Pi model 2 or some other boards but a few need a minimum of 2.5 amps. Just check the outlet rating and the power needs of the board you use and make sure the outlet has more. Cheers.
Awesome, thank you very much.
if you connect the red and the black wire, it will go on.
What about PoE (Power over Ethernet) as an optional way to power one of these?
-Hi. In standard form POE is not an option. POE runs about 48V which is was outside the voltage tolerance of any of these boards. You could do an old hack using ethernet cabling though. You only use 4 of the 8 wires in an ethernet cable anyway so the idea is you splice out the other 4 wires at both ends and pump the required voltage through those 4 wires and keep the ethernet going through the other 4. You end up with comms through part of the cable and power through the other part. There are limits to how much current and how far you can push the power but it works. Cheers.
The new raspberry pi 3 B+ has PoE
- Yes a nice option!
that BASS though in your intro; slaps bro. dang! also, way too loud
Can I plug into the barrel jack as well?
Hi. Not many of these boards have barrel jacks for power, mostly mini and micro USB, GPIO etc. Arduino Uno etc have barrel jacks as power input. Just make sure that any barrel jack on whatever board you're using is for power and not video or audio. Cheers.
@@michaelsstuff4402 I'm glad I asked and you answered ... or I might have tried to jam a 5V barrel jack into the audio connector ;-)
does it matter which 5 volt pin i use?
- Hi. You can use either of the 5V GPIO pins. Cheers.
ITS HIGH NOON
I don’t have that type of port I have the circular one
I have laptop universal charger with usb out on the brick. Under the usb is this info 5v2a.Can i run RP3 model b with this?
- Hi. Good chance the answer is no. For a happy Pi 3 you want 2.5A output and the rated output on your brick would likely be a little under 2A. You could get away with a Pi2 though. Cheers.
My Electronics & Hacking Show tnx :)
@@michaelsstuff4402 popular peoples used 5v 3 A wall power supply whit rasbi 3, 2,5 its ok, but better use 3A supply.
My phone charger has: input 100 - 240V 1.1A 50-60 Hz
Output: 5V == 8A
Can I use that?
- If it really has an output of 8A then yes it will provide more than enough power. Cheers.
that is like more than double though right?
Can you up the amps at all to run more devices?
- If you mean run more devices from the power source itself then yes, its just a power source. If the voltage and current reaching the board is sufficient then all good. If you mean feed more power to the board so you can run more USB devices from the board, then not really as most boards have a limitation as to how much their USB ports (combined) can handle. Cheers.

Great video anyway and ty in advance!
- Hi. It's possible that it will work but I can see problems such as draw being demanded from the smaller power supply that exceeds its ability and it burns out. It would only take a second or so. If you had to use 2 power supplies I would use two the same and connect them together in parallel and connect them to the same point on the Pi, not different points. In essence you end up with a 4.2A power supply. Cheers.

Can I charge a raspberry pi with a standard phone charger
Hi. You can power a Pi with a 5v phone charger as long as the phone charger has sufficient amperage. A Pi 2 will work with about 1A. A Pi 3 will require more as will a 4. If you don’t have sufficient power going to the Pi, the Pi might fail to start or become unstable. Cheers.
Will 1A be sufficient for model 3b+?
- No. The Pi 3's need 2.5A. Cheers.

Is the mi power bank 2 (10000mah) able to power the Raspberry pi 3?
- Hi. The Pi 3 requires 5V at 2.5A to run without issue. The power bank you mentioned delivers 5.1V at 2.4A ideally. I have run a Pi 3 with a slightly under powered supply before with no real issue so I will say yes this power bank will run a Pi 3. The only factors to consider is, does the power bank really deliver the claimed power and if you use a cheap low quality usb cable you will introduce further power loss going to the Pi. Cheers.
