COM.NB-IoT
SKU:M031-B
Description
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.
COM.NB-IoT RXD/TXD can be connected to M5Stack's UART (TX(0/13/17)RX(5/15/16)) by setting the DIP switch, GPIO in M5Stack Fire 16/17 It is connected to PSRAM by default. It is recommended to use any one of the remaining two groups of pins.
Dial the DIP switch on the side of the audio configuration pin to ON when in use
