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.
