<p><b>New page</b></p><div>Is it possible to turn the power off and on from the external microcontroller? I am building an external watchdog to oversee the operation of the raspberry pi. When the system hangs up, I would like to turn off power to the raspberry pi with an electrical signal (+5V or +3.3V), coming from an external microcontroller. After that I would like to turn the power on again also from external microcontroller. Is this approach possible on this board?<!-- migrated from Comments; original IP: 178.6.28.187 --></div>178.6.28.187
