Supported. SDA & SCL pads on front side. Used for magnetometer, sonar, etc.
Traditional Betaflight LED Pad
Supported. 5V, G and LED pads on bottom of the front side. Used for WS2812 LED
controlled by Betaflight firmware.
Buzzer
BZ+ and BZ- pad used 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 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.
RSSI Input
Supported. Named as RS on the front side.
SmartPort
Use any TX pad of UART for the SmartPort feature.
