[Introduction]:E90-DTU (400SL22-GPRS) is a data transmission station from radio frequency to GPRS network server, which realizes the transparent data transmission between sub-1g and GPRS network. The sub-1g radio frequency transceiver is based on SEMTECH SX1262 radio frequency chip and supports LoRa spread spectrum technology.
