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.

[A]. Press and hold BOOT button and power the FC on at the same time will force the FC to enter DFU mode, this is for firmware flashing when the FC gets bricked.
[B]. When the FC is powered on and in standby mode, the BOOT button can be used to controller the LED strips connected to LED1-LED4 connectors on the bottom side. By default, short-press the BOOT button to cycle the LED displaying mode. Long-press the BOOT button to switch between SpeedyBee-LED mode and BF-LED mode. Under BF-LED mode, all the LED1-LED4 strips will be controlled by Betaflight firmware.
