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.
