The serial port level is 3.3V TTL logic level
I2C are all 3.3V TTL logic levels
GPIO high level is 3.3V, GPIO is directly drawn from Xavier
CAN with transceiver
The I2C device file is I2C-0
The mapping files in the /dev directory corresponding to UART1 and
UART2 are ttyTHS0, ttyTHS1, and UART3 is the debug port
Xavier: The mapping numbers of GPIO06, GPIO07, GPIO08, and
GPIO10 in the system are: 253, 254, 256, 258
Xavier industrial: The mapping numbers of GPIO06, GPIO07,
GPIO08, and GPIO10 in the system are: 253, 254, 256, 258
