Wireless COMMU Module Extend RS485/TTL CAN/I2C Port with MCP2515 TJA1051 SP3485 Development Board EP

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.

Be care about TTL Interface. It is a UART Interface actually by default. But you can switch it to connect with UART2 after changed those jumpers(J6, J7, J9, J10).
