SpeedyBee F405 V3 Flight Controller 30x30


  • BOOT Button: Supported.
    [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 control 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.
  • Blackbox MicroSD Card Slot: *Betaflight 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 Betaflight can only recognize 4GB maximum. We suggest you use this 3rd party formatting tool and choose ‘Overwrite format’ and then format your card. Also, check out here for the recommended SD cards or buy the tested cards from our store.
