Note RS232

Connect TX/RX PIN connector to the UART 232 port on J31 

minicom -s
Disable Hardware Flow Control and set Serial Device to /dev/ttySTM3. Check that characters typed from keyboard are echoed in the terminal.

Note RS485

Tested /dev/ttySTM1 with another RS485 device. Configure minicom: 

minicom -s
Configure the Serial Port Setup as shown: RS485 minicom config

Note CAN

Connect CANBUS pins on J33 to a compatible transceiver.
