[Introduction]:E90-DTU(400SL42) is a real high-quality industrial-grade wireless data transmission radio. The radio adopts LORA spread spectrum technology. Its strong anti-interference ability makes wireless communication more stable and reliable in industrial sites. It has a variety of transmission methods, works in the (410.125~493.125MHz) frequency band (default 433.125MHz), and the radio station provides a transparent RS232/RS485 interface. LoRa direct-sequence spread spectrum technology will bring a 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 ability, greatly improving reliability and transmission distance. The radio has the function of data encryption; it supports the setting of packet length, and supports different real-time and data packets.

[Transmission power]:15W

[Communication distance]:30km
