E90-DTU(400SL33) is a wireless data transmission radio using military-grade LoRa modulation technology. It has a variety of transmission methods and works in the (410.125~493.125MHz) frequency band (default 433.125MHz). The radio provides transparent RS232/RS485 interface, supports 8
~28V voltage input.
LoRa direct-sequence spread spectrum technology will bring longer communication distance, and has the advantages of concentrated power density and strong anti-interference ab![](https://ae01.alicdn.com/kf/S5eee1eb96dbc49659f7a6cf5a13b4c76Q.jpg?width=950&height=2735&hash=3685)
