Connect the switch wires to 5V0 and PWRON signals on the 30pin header for the system power on/off.
https://wiki.odroid.com/odroid-xu4/hard ... _2x15_pins

But the blue LED in the button will not turn on since all the GPIO output is 1.8Volt only.
The LED need 2.5Volt at least.

Connect 5V0 output to the LED anode via 200~500Ohms resistor.
The LED cathode must be connected to a GND pin.
