*Betaflight firmware requires the type of microSD card to be
either Standard (SDSC) or High Capacity (SDHC), so extended
capacity cards (SDXC) are not supported(Many high-speed U3 cards
are SDXC). Also, the card MUST be formatted with the FAT16 or FAT32
(recommended) filesystems. 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.
