 ## Description
 
-**COM.LoRaWAN470** is a LoRaWAN communication module suitable for 470MHz frequency launched by M5Stack. The module adopts the Ai-Thinker Ra-07 module solution, which supports long-distance communication and has both ultra-low power consumption and high sensitivity. The module integrates the LoRaWAN protocol stack and adopts a serial communication interface (using AT command set for control), and can be used as a collection node to access a large number of gateways for data collection and management.
