8 == What is LA66 LoRaWAN Module ==
9
10 **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 LoRa 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 program, create and connect your things everywhere.
11
12 **LA66 **is a ready-to-use module which includes the LoRaWAN v1.0.4 protocol. External MCU can use AT command to call LA66 and start to transmit data via the LoRaWAN protocol.
13
14 **Each LA66 **module includes a world unique OTAA key for LoRaWAN registration.
