Dragino LA66 LoRaWAN USB


The 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.


  • LA66 is a ready-to-use module that includes LoRaWAN v1.0.3 protocol. External MCU can use AT command to call LA66 and start to transmit data via the LoRaWAN protocol.
  • Each LA66 module includes a world-unique OTAA key for LoRaWAN registration.
  • Besides the support of the LoRaWAN protocol, LA66 also supports open-source peer-to-peer LoRa Protocol for the none-LoRaWAN application.
  • LA66 is equipped with TCXO crystal which ensures the module can achieve stable performance in extreme temperatures.
