E90-DTU(400SL47) Ebyte 70 Km LoRa module remote communication SX1268 radio frequency chip 485/232 Wireless data transmission

E90-DTU(400SL47) LoRa module remote communication SX1268 radio frequency chip 485/232 wireless data transmission radio relay network [Interface type]：RS232/RS485 [Working frequency]：433.125M [Communication distance]：70km [Product size]：160*137*44mm [Product weight]：846.2g±5g [Introduction]：E90-DTU (400SL47) is a truly high-quality industrial-grade wireless data transmission radio (the radio won the national design patent ZL202030009845.3). The radio uses LORA spread spectrum technology, and its strong anti-interference ability allows wireless communications to be used in industrial sites. More stable and reliable. It has a variety of transmission methods and works in the (410.125~460.125M) frequency band. The radio station provides a transparent RS232/RS485 interface. The radio has a data encryption function. The data transmitted by the radio in the air is random. Through strict encryption and decryption algorithms, data interception is meaningless. It supports packet l
