It's ridiculous
clean eating.
Just look at FC!

DJI Air Unit Connection Mode | Two modes are supported: 6-pin connector or direct soldering. |
DJI 6 Pin Air Unit Plug | Supported. Fully compatible with DJI O3/RunCam Link/Caddx Vista/DJI Air Unit V1, no need to replace any cables. |
Blackbox MicroSD card slot | *Betaflight firmware requires the microSD card type to be Standard (SDSC) or High Capacity (SDHC) less than 32GB, so Extended Capacity (SDXC) cards are not supported (many high speed U3 cards are SDXC). Also the microSD card MUST be formatted with FAT16 or FAT32 (recommended), you can use any SD card less than 32GB, but Betaflight can only recognize a maximum of 4GB. We suggest you use this 3rd party formatting tool and choose "Overwrite format" then format the card. Also check here for recommended SD cards or purchase tested cards from our store. |
Current sensor input | Supported. For SpeedyBee BLS 55A ESC, set scale = 400 and Offset = 0. |
Power input | 3S - 6S Lipo (via G, BAT pin/pad from 8-pin or 8-pad connector on the bottom side) |
5V output | 9 groups of 5V outputs, four +5V pads and 1 BZ+ pad (used for buzzer) on the front side, and 4 5V LED pads. The total current load is 3A. |
9V output | 2 sets of 9V outputs, one +9V pad on the front side and the other included in a connector on the bottom side. Total current load is 3A. |
Output 3.3V | Supported. Designed for 3.3V input receivers. Current load up to 500mA. |
Output 4.5V | Supported. Designed for GPS receiver and module even when the FC is powered by USB port. Current load up to 1A. |
ESC signal | M1 - M4 on the bottom side and M5-M8 on the front side. |
UART | 6 sets (UART1, UART2, UART3, UART4 (dedicated to Bluetooth connection)), UART5 (dedicated to ESC telemetry), UART6 |
ESC Telemetry | UART R5(UART5) |
I2C | Supported. SDA and SCL pads on the front side. Used for magnetometer, sonar, etc. |
Traditional Betaflight LED Mat | Supported. 5V, G and LED pad on the bottom of the front side. Used for WS2812 LED controlled by Betaflight firmware. |
Buzzer | BZ+ and BZ- pad used for 5V buzzer |
START button | Supported. [UN]. Press and hold the BOOT button and power on the FC at the same time to force the FC to enter DFU mode, this is for flashing the firmware when the FC is frozen. [B]. When the FC is powered 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 toggle the LED display mode. Long press the BOOT button to switch between SpeedyBee-LED mode and BF-LED mode. In BF-LED mode, all LED1-LED4 strips will be controlled by the Betaflight firmware. |
