The RS485 Shield for Arduino is a reliable communication expansion board designed specifically for the Arduino Uno and compatible boards. This shield enables UART-to-RS485 conversion, allowing your Arduino to communicate with industrial RS485 devices over long distances with high anti-interference performance and stable data transmission.
Built with standard and mini RS485 ports, RS485 headers, and a flexible welding area, this shield offers convenience and adaptability for both standard applications and custom DIY designs. With a switchable automatic/manual transmission mode, users can fine-tune control based on their system requirements.
