SDA, SCL pads on the front. For magnetometers, sonar, etc.Legacy Betaflight LED Pads: Supported. 5V, G, LED strip on the bottom of the front. For BF control WS2812 LED lightBuzzer:Support .BZ+ , BZ- pad used for 5V buzzerBOOT key:Supporte.Pre and hold the BOOT key to power on, you can enter the DFU mode, which is used to save the brick and flash the firmware; in the power-on standby state, the BOOT key is also used to control the LED strips connected to the D1-D4 pads on the four corners of the PCB. By default, short pre the BOOT key to cycle through the LED display status; Changan BOOT key switches the LED control mode: SpeedyBee LED or BF LED. In BF LED mode, these LED strips will be controlled by BF firmwareRSSI pad:Support. Labeled as RSSmartPort:Support.
