      Hi, So i have a ISO RS485 and i need to get modbus working on it. The primary problem im facing is that the module is UART based and by my understanding M5Dial has I2C and GPIO ports. Is it as simple as hardware serial and setting 1 and 2 pins to UART or is there something else to it
      Also it would be great help if there are any modbus library that can be used.
      Thank You

            Hello @mukul_100_

            please find an example here with M5Dial and RS485 unit controlling an ACSSR relay via Modbus protocol.

            Thanks
