	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.
