20 (% style="color:blue" %)**LA66 USB LoRaWAN Adapter**(%%) is designed to fast turn USB devices to support LoRaWAN wireless features. It combines a CP2101 USB TTL Chip and LA66 LoRaWAN module which can easy to add LoRaWAN wireless feature to PC / Mobile phone or an embedded device that has USB Interface.

23 (((
24 (% style="color:blue" %)**LA66**(%%) is a ready-to-use module that includes the (% style="color:blue" %)**LoRaWAN v1.0.3 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 to make stable LoRaWAN Sensors to support different LoRaWAN servers and different countries' standards. External MCU can use AT command to call LA66 and start to transmit data via the LoRaWAN protocol.
