Ebyte E90-DTU(900L20)-V8 20dBm RS232/RS485 LoRa Spread Spectrum Technology 868MHz/915MHz LoRa wireless data transmission radio

E90-DTU(900L20)-V8 Ebyte LoRa 868M wireless communication radio communication terminal RS232/RS485 interface [Communication interface]：RS232/RS485 [Working frequency]： 862~930MHz [Transmitting power]：20dBm [Communication distance]： 5km [Product size]： 82*62*25mm [Introduction]：E90-DTU(900L20)-V8 is a high-speed 868M wireless data transmission 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 transmission radio has the characteristics of FEC forward error correction, data encryption and compression function, long transmission distance, and strong communication reliability. Send Inquiry Purchase File DownloadsCompare Specification Parameters Pin Definition Order Way File Downloads Series Products serial number project Specification illustrate 1 Product size 82*62*25mm For details, see 3.2.
