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.
