This module interfaces an Arduino or similar microcomputer to RS-485. RS485 is used for Serial Communications over longer distances than direct RS232 or TTL, and supports multiple units on the same bus (Multi-Drop). Multiple Units can be connected to the same RS-485 wiring. ...
In this comprehensive tutorial, we will delve into the world of Modbus RTU RS485 protocol integration with the versatile ESP32 board, all within the familiar confines of Arduino IDE. We'll embark on a journey through the fundamental concepts of the Modbu
wiring diagram on the back facilitates quick setup, and the use of anti-static bag packaging ensures safe and reliable delivery. Whether you're working on a wifi module arduino project or integrating the module with an A4988 Arduino code, the MAX3485 Module for Arduino is a reliable choice ...
1、RS485介绍 RS485是有线传输串行数据的标，支持同时传输485总线上的多点数据。传输速率为10Mbps，传输距离可达50英尺。传输速率为100Kbps时，传输距离可达4000英尺。RS485总线通常为4芯或2芯，现在普遍采用2芯总线。一条总线最多支持32个设备。总线之间还可以串接，从而支持成百以上的节点。RS485主要技术规格如下...
You will of course also need two USB cables to connect both Arduinos up to your PC at the same time. Master RS-485 Device Software /* * RS485 Master Software * Exercise the MAX485 Module. This code runs on the first (Master)device. * Use the RS485_Slave_Test software for the ...
