Description
COMMU is a Muti-Communication-Interface-Converter. Integrated with 2IIC, 1TTL, 1CAN, 1RS485. Apparently COMMU has packed with most of series communications.
Default connection: TTL – UART0, RS485 – UART2. Since ESP32 pin map is allowed for re-assign, you can re-assign or re-mapping the TTL or RS485 interface to other pins.
