Specifications:
BOOT Button: Supported.
[AND]. Press and hold the BOOT button and power on the FC at the same time, this will put the FC into DFU mode, this is for flashing the firmware when the FC freezes.
[B]. When the FC is powered on and in standby mode, the BOOT button can be used to control the LED strips connected to the LED1-LED4 connectors on the bottom. By default, short press the BOOT button to toggle the LED display mode. Long press the BOOT button to switch between SpeedyBee-LED mode and BF-LED mode. In BF-LED mode, all LED1-LED4 strips will be controlled by Betaflight firmware.
Blackbox MicroSD Card Slot: *Betaflight firmware requires the microSD card type to be either standard (SDSC) or high capacity (SDHC), so extended capacity (SDXC) cards are not supported (many high speed U3 cards are SDXC). The card MUST also be formatted with a FAT16 or FAT32 file system (recommended). So you can use any SD card smaller than 32GB, but Betaflight can only recognize a maximum of 4GB. We suggest you use this third-party format tool, select 'Overwrite Format' and then format the card. See also recommended SD cards here or buy tested cards in our store.
