E90-DTU(900SL42)LoRa data transmission radio LoRa module remote communication SX1262 radio frequency chip 485/232 wireless data transmission radio relay network

[Introduction]：E90-DTU(900SL42) is a truly high-quality industrial-grade wireless data transmission radio. The radio uses LORA spread spectrum technology. Its strong anti-interference ability makes wireless communications more stable and reliable in industrial sites. It has a variety of transmission methods and works in the (850.125~930.125MHz) frequency band (default 868MHz). The radio station provides a transparent RS232/RS485 interface. LoRa direct sequence spread spectrum technology will bring longer communication distance and has the advantage of strong anti-interference ability. The module has a software FEC forward error correction algorithm, which has high coding efficiency and strong error correction capability, which greatly improves reliability and transmission distance. The radio has data encryption function; supports sub-packet length setting, supports different real-time and data packets.
