E90-DTU(900SL22-GPRS) Ebyte high speed wireless iot communication device RF to GPRS network server 868 915 mhz lora gateway



[Transmission type]:GPRS

[Interface Type]:RF to GPRS


[Introduction]:E90-DTU (900SL22-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.
