3.3.14 Power and Reset buttons

Power and Reset Connector - J30
Pin Signal
1 ON_OFF
2 GND
3 RESET#
ON_OFF: Power switch input signal, open drain. 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.
RESET#: Reset switch input signal. This signal has to be connected to an external momentary pushbutton (contacts normally open). When the pushbutton is
pressed (i.e., the signal is connected to GND), the pulse of Reset signal will cause the reset of the board.
Please be aware that the power switch input signal and the reset switch input signal are also managed directly on the carrier board by the two pushbuttons SW2
and SW1 (respectively), so it is not mandatory to connect them externally using J30. Anyway, reset switch SW1 is optional.
