| 6 | |||
| 7 | == What is LA66 LoRaWAN Module == | ||
| 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 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. | ||
