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.
Notice
?
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.
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);
//Initialize Serial according to the actual connected pins
Serial2.begin(115200, SERIAL_8N1, 13, 14);
The module base has a DC power input interface. Please strictly follow the input range (5-12V) to prevent damage to the module
when using this interface to connect to the power supply. The internal power DIP switch can adjust the voltage level of the internal
terminal VIN to adapt to different modules.
