Power On/Off connector
To allow the integration of a SBC-C20 based system inside a box PC-like, there is a connector on the
board that allows remoting the signal for the Power Button
The dedicated connector is a 2-pin male connector, type MOLEX p/n 53047-0210 or equivalent, with
pinout shown in the table on the left.
Mating connector: MOLEX 51021-0200 crimp housing with MOLEX 50079-8000 crimp terminals.
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.
