It is designed to facilitate developers to quickly deploy industrial-level LoRaWAN and IoT solutions. It helps users to turn the idea into a practical application and make the Internet of Things a reality. It is easy to create and connect your things everywhere.

This mature LoRaWAN stack greatly reduces the risk to make stable LoRaWAN Sensors to support different LoRaWAN servers and different countries' standards. External MCU can use AT command to call LA66 and start to transmit data via the LoRaWAN protocol.
