E95M-DTU(400SL22-485) Wireless digital radio station LoRa spread spectrum, AT command, serial port online upgrade, 433MHz global unlicensed frequency band, small size rail-mounted radio, transmitting power 20~30dBm

[Introduction]：E95M-DTU (400SL22-xxx) is a wireless data transmission radio using military-grade LoRa modulation technology. It has a variety of transmission methods and works in the (410.125MHz~493.125MHz) frequency band (default 433.125MHz). The radio provides transparent RS485/RS232/ TTL interface, adopts plastic shell, rail-mounted structure, supports 8~28V (DC) wide voltage input. LoRa spread spectrum technology will bring longer communication distance and has the advantage of strong anti-interference ability.
