[Introduction]：E95-DTU (900SL30-232) is a wireless data radio using military-grade LoRa modulation technology. It has multiple transmission modes and operates in the frequency band (850.125MHz~930.125MHz) (default 868.125MHz). The data radio provides a transparent RS232 interface, uses a plastic shell, a guide rail installation structure, and supports DC 8~28V voltage input. LoRa spread spectrum technology will bring a longer communication distance and has the advantage of strong anti-interference ability.
