[Introduction]:E90-DTU (230SL22-GPRS) is a wireless radio to GPRS network server data transmission station, which realizes the transparent transmission of Sub-1G and GPRS network data. It supports LoRa spread spectrum technology and is equipped with a high-performance MCU internally. It has a variety of transmission methods, a built-in power amplifier (PA) and a low-noise amplifier (LNA), and the measured communication distance is up to 5km.
