7 +== What is LA66 LoRaWAN Module ==
8 8  
9 +**Dragino LA66** is a small wireless LoRaWAN module that offers a very compelling mix of long-range, low power consumption, and secure data transmission. 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.

11 +**LA66 **is a ready-to-use module that includes the LoRaWAN v1.0.4 protocol. The LoRaWAN stack used in LA66 is used in more than 1 million LoRaWAN End Devices deployed world widely. This mature LoRaWAN stack greatly reduces the risk for developers to make a LoRaWAN End device. External MCU can use AT command to call LA66 and start to transmit data via the LoRaWAN protocol.
