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 using with the FIRE main control, due to the PSRAM pin conflict, please switch the Module base DIP switch pin to TX(0/13), RX(5/15) when using it.
When used with Core2 series main control, due to the different order of the base pin array, COM.NB-IoT base pins TX(16), RX(17) correspond to the actual pins TX(14) of the Core2 main control ,RX(13).
Note: When using the CORE2 or CORE2-FOR-AWS main control to drive the module, please use the DC power input of the base and set the power mode to input mode (refer to the code below), otherwise it will not start normally. //mbus_mode_t: //kMBusModeOutput: use USB or battery power //kMBusModeInput: Use external power supply 5V, or DC interface M5.begin(true, true, true, false, kMBusModeInput);
Dial the DIP switch on the side of the audio configuration pin to ON when in use

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.
