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 this3rd party formatting tooland choose ‘Overwrite format’ then format your card. Also check outherefor the recommended SD cards or buy thetested cardsfrom our store.
