*Beta flight firmware requires the type of the 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 Beta flight 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.
