Fix a DEAD Raspberry Pi..!

Hi guys,

While doing a project based on raspberry pi i just overvoltaged it and got damaged. And now i figured out a way to fix dead pi's damaged by excessive power supply. In my case it's a pi 3 model b, If you like this please vote me for micro controller contest

Step 1: Gather Materials..

• Raspberrypi (which ahve to be fixed)
• Arduino Uno
• Sorldering machine
• etc

Step 2: Issue..

The reason why my pi damaged was giving power from both GPIO pins and usb connector.

Step 3: Precaution..

The diode BUZG550 is the one we have to replace to make pi working so we have to replace it with SMBJ.A0 or M7 seen in Arduino. Both are ideal solution to make it working. Please do not damage the board while working on this fix.

Step 4: Applied Fix!

Step 5: Conclusion

This fix helped me a lot and saved my money and time, I think tho post this instructables because this would help someone i think. If it helps please share and like this instructables

Hi, my raspi dead after lightning, i follow your step, replace with diode 1n4007 and back alive, green indicator blinking. But all component around it become hot include the power cable. I remove the diode and still same, led blinking but hot around it. Do you have any clue about it?

It worked also for my dead rpi4. Thank you for this, you saved me lot of money.

Hi. Where was the diode on the PI4?
Cheers

You use diode m7?

[maximilian.yakovski]

Be honest I dont know. I took a diode from Arduino (from china store) and insert it to rpi4 and it works.

did you test the diode first using a multimeter?

This is really nice...
Is that a standard power diode, or a Zener? -Couldn't find a data sheet for it....
I have a couple of Arduinos, but I don't particularly want to sacrifice them for this!

Thank you! I run a lab and have thrown out several PIs. I will have to keeep this for future use.
