Can anyone throw some light on the pad marked "RUN" next to the composite TV pads on the PiZero. Is this the same as the reset pin on Pi 2's etc. Is this pin the best way to shutdown the PiZero safely?
PiZero Reset/Run pin
These pins are the same as the run pins on every other raspberry pi (2B, B+, ...). You can't shutdown from them, you can only do a hard reset or start the raspberry pi from them.
