[Introduction]：E90-DTU (230SL42) is a truly high-quality industrial-grade wireless data transmission radio (the radio won the national design patent ZL202030009845.3). It adopts LORA spread spectrum technology and its strong anti-interference ability makes wireless communication more convenient in industrial sites. Stable and reliable. The radio has a variety of transmission methods and provides transparent RS232/RS485 interfaces. LoRa direct sequence spread spectrum technology will bring longer communication distance and has the advantage of strong anti-interference ability. It has data encryption function and FEC forward error correction algorithm, which greatly improves security, reliability and transmission distance.
