DJI Air Unit Connection Way |
Two ways supported: 6-pin connector or direct soldering. |
|
6-pin DJI Air Unit Plug |
Supported. Completely compatible with DJI O3/RunCam Link/Caddx Vista/DJI Air Unit V1 no wire is needed to be changed. |
|
Blackbox MicroSD Card Slot |
*Betaflight firmware requires the type of the microSD card to be either Standard (SDSC) or High capacity (SDHC) under 32GB so extended capacity cards (SDXC) are not supported(Many high-speed U3 cards are SDXC). Also the microSD card MUST be formatted with the FAT16 or FAT32 (recommended) format you could use any SD card less than 32GB but the Betaflight can only recognize 4GB maximum. We suggest you use this and choose ‘Overwrite format’ then format your card. Also check out for the recommended SD cards or buy the from our store. |
