For BiBoard V0

Hardware Connection

Please connect the corresponding pins of the Raspberry Pi and the BiBoard extension hat 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.
