COMMU Module Extend RS485/TTL CAN/I2C Port
- PRODUCT DETAILS
COMMU is a Muti-Communication-Interface-Converter. Integrated with 2I2C, 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).

LEARN AND DOCUMENTS
The shipment was very quick. The modules still not tested.
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....
