97 +If user doesn't have LA66 USB Adapter, they can still use other Dragino Device to connect to PC for OTA update. Steps:
98 +
99 +* Find the suitable mode which base on LA66 chip ( All LoRaWAN model with LB or LS suffix , such as SN50v3-LB)
100 +* Update the LA66 USB OTA firmware to the device.
101 +* Connect the device to PC via UART interface.
102 +* Make sure power off or update the firmware back to original firmware , because the LA66 USB OTA fimware is not low power consumption firmware. it will consume the battery very fast.
