350		-* We ship the LA66 USB LoRaWAN Adapter with a boot loader by default, and the latest boot loader is V1.4. Users can download the new version of the boot loader by clicking on this [[link>>https://www.dropbox.com/scl/fo/ztlw35a9xbkomu71u31im/AFhmjtEOaipfBAFrpMCoWrI/LoRaWAN%20End%20Node/LA66%20LoRaWAN%20module/Firmware/OTA_Firmware?dl=0&rlkey=ojjcsw927eaow01dgooldq3nu&subfolder_nav_tracking=1]].

373		-=== 1.10.2 Update method: For LA66 without bootloader ===
374		-
375		-
376		-* Explanation:
377		-
378		-For LA66 without a bootloader, we can only burn a bootloader for it in the following way. Because using OTA_Tool to upgrade the firmware of LA66 this address is (% style="color:blue" %)**0x0800D000**(%%) by default, but our bootloader needs to be burned at address .
379		-
380		-Therefore, you can use this method to download the firmware with the boot loader directly or upgrade your boot loader (address from (% style="color:blue" %)**0x08000000**(%%)).
