Module COMX LoRaWAN915
SKU:M031-C3
Description
Module COMX LoRaWAN915 is a LoRaWAN communication module launched by M5Stack for the 915MHz 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), making it suitable for data collection and management as a collection node when connected to a gateway in large quantities. It provides an external power interface (with a toggle switch to adjust between 5V/12V power input), making it 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), RX(G5/G15).
Frequency Band
The product supports the US915 band by default and does not support AU915.

Power Switching
The module base has a DC power input interface. When using this interface to connect to a power source, 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.
