## Overview

The DFROBOT RS485 Shield for Arduino is a powerful accessory that transforms your Arduino into a robust communication hub, enabling seamless interaction with industrial devices through reliable UART/Serial to RS485 conversion.

## Description

INTRODUCTION  RS485 is an industrial standard for long distance, anti-interference and reliable communication. So we create this RS485 Arduino shield, especially designed for the Arduino controller board. It converts UART/Serial protocol to RS485 protocol. This board allows Arduino access to industrial standard protocol easily.   In contrast to RS-422, which has a single driver circuit which cannot be switched off, RS-485 drivers use three-state logic allowing individual transmitters to be deactivated. This allows RS-485 to implement linear bus topologies using only two wires. The equipment located along a set of RS-485 wires are interchangeably called nodes, stations or devices.   - Integrated a standard RS485 port, a mini RS485 port, RS485 headers - Provide the welding areas to make full use of the free space. And more importantly, it's convenient for your DIY design.  - Switch between automatic mode and manual transmission mode, which expand the scope of application.  - Besides Tx/Rx interface, there is a switch to block/disable this shield, when Arduino needs to be programmed.  - Gold immersion PCB. Long pins on the back adapt to most Arduino controllers.   SPECIFICATION  Power module: +5V Module size: 2.16"x2.08" 16 digital IO port (including an I2C interface)  6 analog IO port and power Operation and programming mode switch Automatic and manual transceiver mode switch (When in manual transceiver mode, the enable end is the 2nd digital IO port)  Transceiver indicating LED Standard RS485 interface, mini RS485 interface and RS485 pins Welding area Reset switch PH2.0 sensor interface for DFRobot RS485 series sensor: URM04 Ultrasonic sensor  SHIPPING LIST  RS485 shield x1
