INTRODUCTION

RS485 is an industrial standard for long dsitance anti-interferrence and reliable communication. So we create this RS485 shield especially designed for the Arduino controller board. It can easily convert UART/Serial protocol to RS485 protocol. This board allows Arduino access to industrial standard protocol easily.
  • 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.
