5V MAX485 TTL to RS485 module requires a voltage of 5V and uses 5V logic levels so that it can be interfaced with hardware serial ports of microcontrollers like Arduino.

When initiating transmission, the original ArduinoModbus library (which is designed for a specific Arduino shield) applies hardcoded 50us delay regardless of port speed, which resulted in garbled ...

Arduino DMX There’s only a single piece of cheap hardware needed to add to an Arduino-compatible design to allow it to handle DMX – just an RS485 transceiver chip. There are many of these around us, ...

As a bare minimum an arduino nano and a RS485 driver chip are needed. The Maxim MAX485 or Texas Instruments SN75176 are pin-identical driver chips and can be used either in a DIP8 or SO8 package on ...

In a recent post we interfaced a small DMX RGB LED Par Light with an Arduino Uno through a MAX485 module. In this post we will learn how to work with a compact USB to RS-485 Converter Module. This ...

This paper presents the design and implementation of a scalable energy monitoring system for campus-wide applications, utilizing the Modbus protocol for robust communication. The system incorporates ...
