Official COMMU Module Extend RS485/TTL CAN/I2C Port

Product Description

COMMU is a Multi-Communication-Interface-Converter. Integrated with 2*I2C, 1*TTL, 1*CAN, 1*RS485. 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).

Note

When using with the Core2, the base needs to be removed in order to burn the program properly.
