Power On/Off switch
You can control power supplying to ODROID-C2 while DC adaptor is connected with 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 have an
internal pull-down resistor for default on.
Switch status Output of NCP372
ON(short)
OFF
OFF(open)
ON (+5V)
With this hacking, we strongly recommend to shutdown 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.
Alternative power input
The J8 pins are added for an alternative power input (for easier wiring/soldering to power supply cable
on PCB rev0.2 20160226)
Alternative heartbeat LED
If you want to remap the blue heartbeat LED to other GPIO, refer this great instruction.
