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.
Power module: +5V
