What is RS485 serial communication? How to use RS-485 MODBUS to design Arduino point-point network. Jan 4, 2024 · esp8266, arduino Chrissi28 January 4, 2024, 5:58pm 1 Hello everyone, as I couldn’t really find what I was looking for on the net, I would like to post my ESP8266 Wemos D1 mini project here as an example. Jan 24, 2026 · TTL-compatible inputs and outputs can be made with CMOS structures. ) simply use TTL voltage levels for serial communication. If you look at the datasheets for a 74HC04 and 74HCT04, you will see the different input voltage ranges. I use a Wemos D1 mini together with a TTL to RS485 converter and a RS485 converter to USB as Modbus slave, Home Assistant acts as Modbus master. The takeaway: If you have an input pin whose state does not matter—the circuit will work whether it is held high or held low—then hold it high. gmjnxveepwvsifnqnwoktwpmioazwacoulawavnawwmotuyggpsb
