RS485 is an industrial standard for long distance, 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.









USB-to-RS485 converter with four isolated channels and built-in surge and ESD protection, for stable multi-OS communication in an aluminium alloy case.














Bridge four isolated RS485 buses onto one network cable, with Modbus and MQTT gateway modes built in.
