Power On/Off Switch


You can control power supply to ODROID-C2 while the DC adaptor is connected with an external switch (Sliding or Toggle Switch, for example) if you connect such switch to J4 on the board. J4 is connected to NCP372 (Protection IC). There is an ENABLE pin on the NCP372 and it is a low-active and has an internal pull-down resistor for default on.

Switch status Output of NCP372
ON(short) OFF
OFF(open) ON (+5V)

With this hack, we strongly recommend shutting down the O/S completely before turn-off. Otherwise, the file system could be corrupted very easily. In Linux, for example, please make sure to execute shutdown -r now or poweroff.
