I already know that the run header resets the Pi. My question is does one of the pins lead directly to ground? I would like to use a common ground on the GPIO pins and connect it to the run pin 1.

Is this doable/safe?

You don't say which Pi model you mean. However, I assume (but have not checked) that all run header implementations are the same.

On the Pi 3 Model B one of the run header pins is connected to ground.

See Raspberry Pi 3 Model B (Reduced Schematics):

Raspberry-Pi-3B-V1.2-Schematics

All Pi grounds are connected so it does not matter which ground you use.

  • Indeed I am using a raspberry pi 3. Because of this I was able to use a standard usb cable to run a power switch, reset switch, and power led on 1 common ground. THANKS! – soulgriever Jun 11 '17 at 13:12
