Unit LoRaWAN470 is a LoRaWAN communication module suitable for 470MHz frequency launched by M5Stack. The module adopts the ASR6501 solution, which supports long-distance communication and has both ultra-low capacity and high sensitivity. Communication interface (use AT command set for control), when used, it can be used as a large number of relay gateways to collect samples for data collection and management. This module is suitable for long-distance and low-rate IoT communication applications, such as environmental monitoring, scheduling and deployment.
