I2C

Supported. SDA & SCL pads on front side. Used for magnetometer.

LED Pad

Supported. LED,5V, and GND pads on bottom of the front side. Used for WS2812 LED controlled by Betaflight firmware.

Buzzer

supported,5V,BZ pads for 5V Buzzer

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 controller theLEDstrips connected to LED1-LED4 connectors onthebottom side. By default, short-press the BOOTbuttonto cycle the LED displaying mode. Long-press theBOOT button to switch between SpeedyBee-LEDmode and BF-LED mode. Under BF-LEDmode, all theLED1-LED4 strips will be controlled by Betaflight
firmware.

Supported Flight Controller Firmware
