Hello,
On the Rasberry Pi boards close to the USB ports they have a place where you can solder a header so you can make a reset button to take the Pi out of hibernation. This is useful as it can be used to wake up the PI from shutdown -h, without the need to constantly unplug the power supply.
In examining the Tinkerboard I found what appears to be a spot between the HDMI and power port that are unlabeled. In reviewing the schematics it is very unclear what these pads are for.
The pads closest to the edge have about 5 volts coming off of it. When i short these pads with a wire to simulate a button press it appears the Tinkerboards starts an orderly shutdown. After it powers off, and I short the pads again the Tinkerboard powers up.
The other 2 pads have just a little over 2 volts coming off and shorting these pads seem to have no affect.
Does anyone know the true use of these pads?
