Unit LoRaWAN915 is a LoRaWAN communication module suitable for 915MHz frequency launched by M5Stack. The module adopts the ASR6501 scheme, 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 the AT command set for control). When used, it can be used as a collection node to access a large number of gateways for data collection and management. This module is suitable for long-distance low-power IoT communication applications, such as deployment of environmental monitoring nodes.
