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. 10 10 11 - **LA66**is a ready-to-use module that includes the LoRaWAN v1.0.4protocol. TheLoRaWAN stack used in LA66is used in more than 1 millionLoRaWANEnd Devices deployed world widely. This matureLoRaWAN stack greatly reducesthe risk for developers to make a LoRaWAN End device.
