M031-B Overview
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 with 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.

Frequently Asked Questions
What primary network technology does the M5Stack M031-B module utilize for IoT connectivity? +
The M031-B module is built around the SIM7020G chipset, which is specifically designed for NB-IoT (Narrowband IoT) connectivity. This technology is ideal for low-power, wide-area network applications, providing reliable data transmission for smart sensors and remote monitoring devices that require minimal power consumption and extended battery life in industrial or environmental IoT deployments.
Is the M5Stack COM.NB-IoT module compatible with standard M5Stack development kits? +
Yes, this module is engineered to integrate seamlessly into the M5Stack ecosystem. It uses the M5Stack stackable design, allowing it to connect directly with your existing M5Core controllers via the standardized bus interface. This plug-and-play compatibility significantly reduces your prototyping time and simplifies the assembly of complex IoT gateway solutions in the field.
Does the M031-B kit include the necessary hardware for signal reception? +
The M031-B package comes equipped with an external parabolic antenna, which connects via a standard SMA interface. This high-gain antenna setup is particularly useful for deployments in areas with challenging signal conditions, ensuring that your NB-IoT devices maintain a stable connection to cellular towers even when signal penetration is typically difficult.
What are the primary use cases for deploying the M5Stack SIM7020G module? +
This module is perfectly suited for low-bandwidth IoT applications such as smart agriculture sensors, asset tracking, remote utility metering, and environmental monitoring. Because the SIM7020G supports NB-IoT, it excels in scenarios where devices need to send small packets of data over long distances while operating on battery power for extended periods.
How do I interface with the SIM7020G module for data transmission? +
Communication with the SIM7020G module is primarily handled via AT commands over a UART serial interface. Developers can easily manage network registration, signal strength polling, and data transmission protocols by sending these standard commands from their M5Core controller, providing a familiar and flexible interface for embedded software development.
What is the physical connection standard for the antenna on the M031-B? +
The module features an SMA connector for its antenna interface. This industry-standard connector allows you to use the included parabolic antenna or replace it with other compatible SMA-terminated antennas if your specific deployment environment requires different gain characteristics or physical mounting configurations for your IoT gateway project.
Can the M5Stack COM.NB-IoT module operate in international regions? +
The SIM7020G chipset is a multi-band module designed for global compatibility. It supports a wide range of frequency bands, making it highly versatile for international IoT projects. Before deployment, confirm that your specific local cellular carrier provides support for NB-IoT services within the frequency bands enabled by the SIM7020G firmware.
Does the M031-B module require a specific SIM card format? +
Yes, this module is designed to work with standard SIM card formats compatible with the SIM7020G chipset. Ensure your SIM card is provisioned for NB-IoT data services by your provider, as standard cellular data plans may not support the specific signaling protocols required for efficient NB-IoT operation on this module.
