COM.NB-IoT is a stackable multi-band NB-IoT wireless communication module with built-in SIM7020G communication module. The module supports PSM and eDRX low power consumption modes.
The COM.NB-IoT module has a wide coverage signal. Compared to GSM, NB-IoT has a strong gain, which also enables the product to have wireless communication capabilities in locations such as basements.
The module has a DC power input and can provide 5V-12V power supply through an external power supply. In order to facilitate the user to configure the pin, the DIP switch is used to set the pin. The SIM7020G module is the optimal solution for low latency, low power consumption, and low throughput applications. It is very suitable for IoT applications such as metering, remote control, asset tracking, remote monitoring, telemedicine, and ride sharing.
When used with the FIRE main control, due to the PSRAM pin conflict, please switch the DIP switch pins of the module base to TX(0/13), RX(5/15), and the device can use USB/ External DC is used for power supply.
When used with Core2 series main control, due to the different order of the base pin array, COM.X base pins TX(16), RX(17) correspond to the actual pins TX(14), RX of the Core2 main control (13) The equipment needs to use external DC for power supply.

Arrived on time and works as expected. So far I've only tested 2G connectivity as I am unable to get my hands on a SIM card which would allow it to connect to an NB-IoT network here in Switzerland, but that is hardly M5Stack's fault.
