COMMU is a Muti-Communication-Interface-Converter. Integrated with 2IIC, 1TTL, 1CAN, 1RS485. Apparently COMMU has packed with most of the series communications.
Default connection: TTL - UART0, RS485 - UART2. Since the 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).
|Interface||I2C x2, CAN x1, RS485 x1, TTL x1|

Thanks for fast delivery
Excellent product, thanks!
I bought two of this modules believing they can be programmed using UIFlow as any other module but to my surprise UIFlow does not support it...M5 Stack should properly document their products in this e-commerce website....why is this module not supported on UIFlow while all other modules are?? I will be ready to give a 5 start review once M5 Stack improve product documentation and deliver what they promise....
I have programed Pi's, M0's, M4's and by far, the M5Stack beats them all combined....
Today I gave up my long awaited chance to buy the "fully loaded" Pi-4 to concentrate on bringing the pocket M5Stacks into our operations of industrial control testing and troubleshooting.
Thank you for being the Microprocessor leader that allows us to "Do It Our Way" in measurements, logging, control testing and troubleshooting
