Power On/Off connector
Pin Signal
1 SYS_ONOFF
2 GND
Signals Description:
SYS_ONOFF: Power switch input signal. This signal has to be connected to an external momentary pushbutton (contacts normally open). Upon the pressure of this
pushbutton (i.e., the signal is connected to GND), the pulse of this signal will let the switched voltage rails turn on or off.
Please be aware that the power switch input signal is also managed directly on the board by the pushbutton SW1, so it is not mandatory to connect them externally
using CN47.
