In the right picture, red is pin "1" and green is pin "2".
The serial port level is 3.3V TTL logic level.
GPIO high level is 3.3V and GPIO is directly derived from Xavier
CAN has a transceiver.
The mapping file in the /dev directory corresponding to UART1 and
UART2 is ttyTHS0, ttyTHS1, and UART3 is the debugging port.
The mapping Numbers of GPIO04, GPIO05, GPIO20 and GPIO21 in
the system are respectively:
288, 289, 290, 291
