[Introduction]：E90-DTU(900L30)-V8 is a high-speed 868M wireless data radio (with RS232/RS485 interface), LoRa spread spectrum technology, transparent transmission mode, working in the 862~930MHz frequency band (default 868MHz), working voltage range 8~28V. LoRa direct sequence spread spectrum technology will bring a longer communication distance, and has the advantages of concentrated power density and strong anti-interference ability. The data radio has the characteristics of FEC forward error correction, data encryption and compression functions, long transmission distance, and strong communication reliability.
