M5Stack COM.NB-IoT Module SIM7020G

This is an NB-IoT radio module from the stackable module series by M5Stack, featuring a built-in SIM7020G communication module. Compared with LTE, NarrowBand-IoT is suitable for smaller amounts of data at a lower frequency, but possesses a greater range. The module contains a DC power input and can be powered by an external power supply of 5V-12V. To facilitate pin configuration for the user, DIP switches are provided for setting the serial hardware port pins. The SIM7020G module offers an optimal solution for applications with low latency, low power consumption, and low throughput. It is highly suitable for IoT applications like meters, remote control, equipment tracking, remote monitoring, telemedicine, and carpooling.
