Compatibility with DJI Air Unit | Compatible with all DJI Air units: DJI O3/RunCam Link/Caddx Vista/DJI Air Unit V1. Use the soldering pads < 9V, G, T1, R1, G, SUBS(R2) > on the front right corner of the flight controller to make a pin-to-pin connection with the soldering pads on the DJI Air unit. UART1(T1, R1) is used for OSD and SUBS(R2) is used for the signal input of the internal SBUS receiver of the DJI Air unit. |
Black box | 8MB built-in flash |
BetaFlight Camera Control Panel | Yes (CC pad on the front side) |
Current sensor input | Supported. For SpeedyBee BLS 35A V2 ESC, set Scale=250 and Offset=-500. |
Power input | Li-Po 3-6S. The flight controller is powered via the G, V wires of the 8-pin harness or the G, V pads from the bottom side of the flight controller. |
5V output | 4 groups of 5V output, three +5V pads and 1 BZ+ pad (used for buzzer) on the front side. The total current load is 2A. |
9V output | 1 set of 9V outputs, a +9V pad on the front side. Total current load is 3A. |
Output 3.3V | Supported. Solder plate labeled "3V3" on the front top of the flight controller. Designed for 3.3V input receivers. Current load up to 500mA. |
Output 4.5V | Supported. Designed for radio receiver and GPS module even when the FC is powered by USB port. Current load up to 1A. |
ESC signal | M1 - M4 wires or solder pads on the bottom 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. DA and CL pads on the front side. Used for magnetometer, sonar, etc. |
Traditional Betaflight LED Mat | Supported. 5V, G and LED pads on the bottom of the front side. Used for WS2812 LEDs controlled by Betaflight firmware. |
Buzzer | BZ+ and BZ- pad used for 5V buzzer |
START button | Supported. Press and hold the BOOT button and power on the FC at the same time to force the FC into DFU mode, this is for flashing firmware when the FC is frozen. |
