Module COMX LoRaWAN470
SKU:M031-C2
Description
Module COMX LoRaWAN470 is a LoRaWAN communication module launched by M5Stack, suitable for the 470MHz frequency. The module adopts the ASR6501 solution, supporting long-distance communication while featuring ultra-low power consumption and high sensitivity. The module integrates the LoRaWAN protocol stack and uses a serial communication interface (controlled by AT commands). It can be used as a collection node to connect to gateways in large numbers for data collection and management.
The module provides an external power interface (with a toggle switch to adjust between 5V/12V power input). It is suitable for long-range, low-power IoT communication applications, such as environmental monitoring node deployment.
Note
Compatibility
When used with the Fire controller, due to PSRAM pin conflicts (G16/G17), please switch the module base toggle switch pins to TX(G0/G13) and RX(G5/G15).

Power Supply Switching
The module base has a DC power input interface. When using this interface to connect to a power supply, please strictly adhere to the input range (5-12V) to prevent module damage. The internal power toggle switch can adjust the voltage level of the internal VIN terminal to adapt to different modules.
