Description
The COMMU module is a muti-communication-interface-converter. Integrated with 2I2C, 1TTL, 1CAN, 1RS485. The COMMU works with most of the series communications.
Default connection: TTL - UART0, RS485 - UART2. Since ESP32 pin map can be used to re-assign, you can re-assign or re-map the TTL or RS485 interface to other pins.
It is a UART Interface by default. But you can switch it to connect with UART2 when the jumpers have been changed. (J6, J7, J9, J10).
