| Blackbox MicroSD Card Slot | *Betaflight firmware requires the type of 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. So, you could use any SD card less than 32GB, but the Betaflight can only recognize 4GB maximum. We suggest you use this 3rd party formatting tool and choose 'Overwrite format' then format your card. Also, check out here for the recommended SD cards, or buy the tested cards from our store. |
