The SIM7000G is a low-power cellular/NB-IoT/GNSS module commonly used for IoT, tracking, and remote monitoring projects SIMCom SIM7000G Module is a LPWA module which supports wireless communication modes of Cat-M/NB-IoT/GSM. SIMCom SIM7000G has powerful expansibility with abundant interfaces including UART, GPIO, PCM, I2C etc. it is designed for applications that need low latency, low throughput data communication in a variety of radio propagation conditions. Due to the unique combination of performance, security and flexibility, SIMCom SIM7000E Module is ideally suited for M2M applications, such as metering, asset tracking, remote monitoring, E-health and so on.
