6.1	7	== What is LA66 LoRaWAN Module ==
	8
1.1	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 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.
	10
	11	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.
	12
	13	Each LA66 module includes a world unique OTAA key for LoRaWAN registration.
