Please connect the corresponding pins of the Raspberry Pi and the BiBoard extension hatarrow-up-right as follows:
5V power --> 5V
Ground --> GND
GPIO 14 (TXD) --> RX2
GPIO 15 (RXD) --> TX2
Dial the switch on the BiBoard extension hat to the UART2 side.
To ensure a good connection, you may need to solder the wires.
The software setup and serial port name on Pi are the same as BiBoard V1.
