Module COMX LoRaWAN868 v2.0

SKU:M031-C4

Description

Module COMX LoRaWAN868 v2.0 is a LoRaWAN communication module launched by M5Stack for the 868MHz frequency. The module adopts the ASR6501 solution, supporting long-distance communication while maintaining 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. This module is ideal for long-range, low-power IoT communication applications, such as environmental monitoring node deployment.

Note

Compatibility

When used with the Fire main control, due to PSRAM pin conflicts (G16/G17), please switch the module base DIP switch pins to TX(G0/G13), RX(G5/G15) during use.

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 DIP switch can adjust the voltage level of the internal terminal VIN to adapt to different modules.
