====== UART Console Connector ======
<code>
_____UART____
|Pin 4 - GND|
|Pin 3 - RXD|
|Pin 2 - TXD|
|Pin 1 - VCC|
\___________|

1.8V LVTTL for ODROID-U3/XU3/XU4/X2/X
3.3V LVTTL for ODROID-C1/W

The VCC pin is not a power source but a reference voltage detect.
It is used for detecting the IO voltage.
