Raspberry Pi 3 B+ Short Circuit

ibrahimgarip

Hey i got a new raspi almost 1 week ago and yesterday I try to add cooler fan.

Fan was working 5V and think i can get from pinout. when i was a connect, raspi was restart.

I try again when its open ( Wish i shouldnt image)  and bom, raspi gone. Its not working anymore. Only red light and nothings happening.

I think maybe it can be a short circuit and i measure with multimeter the polyfuse its 0 ohm without power, 0.13 Ohm on power.

I change the sd card and software.

But nothings happened.

What can i do ?

  • The raspberry pi does not have protection on the GPIO pins, so it is easy to short them out and damage the rPi.  Sorry, but I know this from my own bad experience. image After I shorted mine, I searched the web for fixes, but nothing worked.  I hope you have better luck than me.

     

    I have run a fan from the 5v pin (using a different rPi that I didn't damage) and it worked well, it ran for days and did not cause damage.  But it was a very small fan.  If you tried to run a larger fan, the rPi can't supply much power.  The polyfuse protects the incoming power from the USB port, and not the pins.
