COMMU
DESCRIPTION
COMMU is a communication interface converter which can meet most of the application design. Now, COMMU owns two I2C interfaces, one CAN interface and one RS485 interface. Simultaneously, COMMU also owns a TTL level interface. It means you just need to stack it underneath M5Core when you want to control a CAN device or RS485 device.
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).

- 2x I2C Interface
- 1x CAN Interface
