ES32C14 FAQ
Share
Hello, I have another question for a development project. I need a device that acts as a Modbus master. The device must have at least 6 inputs and an LED and perhaps a Relay output. The supply voltage should also be 230V and housed in a DIN rail housing. As well as the RS485 connection. I'll let you know what it's supposed to control. Do you think you can build something like that with the hardware?
Answer :
You may need an ESP32 expansion board with RS485 and IO interfaces.

Question :
They all have only 4 digital inputs, I need at least 6 digital inputs and also if possible a bit smaller board .
