*Note: BOOT button. Options for use: [A]. Press and hold the BOOT button and power on the FC at the same time to force the FC into DFU mode, this is to flash the FC when the firmware is flashed.
[B]. When the PC is 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 side. By default, short press the BOOT button to enter LED display mode. Press and hold the BOOT button to switch between SpeedyBee-LED mode and BF-LED mode. In BF-LED mode, all LED1-LED4 lines will be controlled by Betaflight firmware.
