E90-DTU(400SL30-GPRS) Ebyte 30dBm 10km Range Wireless 433Mhz M2M Industrial Cellular GPRS 4G Modbus MQTT LTE IOT LoRa Gateway




[Interface]:RF to GPRS

[Product weight]:257±5g

[Introduction]:E90-DTU (400SL30-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.
