[Introduction]：EWD95M-400SL22 (485) is a wireless data transmission radio using military-grade LoRa modulation technology. It has multiple transmission modes and operates in the (410.125MHz～493.125MHz) frequency band (default 433.125MHz). The radio provides a transparent RS485/RS232 interface, uses a plastic shell, 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.
