[Introduction]：EWD95M-400LN22(485) is a wireless data transmission node radio designed with LoRaWAN technology. It supports CLASS-A/CLASS-C node types, ABP/OTAA network access methods, 410~510MHZ working frequency band, and supports LoRaWAN 1.0.3 EU433/CN470 standards. The radio provides a transparent RS485/RS232 interface. Users can access the standard LoRaWAN network through simple configuration of AT commands. It uses a plastic shell and a guide rail installation structure, and supports 5~28V (DC) wide voltage input. LoRa spread spectrum technology will bring a longer communication distance and has the advantage of strong anti-interference ability. The product is sprayed with three anti-paints, with functions such as "anti-mildew", "anti-moisture" and "anti-salt spray".
