IMU(Gyro):
ICM42688P
USB Port Type:
Type-C
Barometer:
Included
OSD Chip :
AT7456E chip
BLE Bluetooth :
Supported. Used to connect with the SpeedyBee App for flight controller and ESC parameter configuration. Please ensure the MSP switch on UART 4 is enabled and set to 115200 baud, otherwise, the Bluetooth function cannot be used.
DJI Air Unit Connection Way :
Direct soldering
6-pin DJI Air Unit Plug :
Compatible with all DJI Air Units: DJI O3/RunCam Link/Caddx Vista/DJI Air Unit V1. Please connect the solder pads < 9V, G, T1, R1, G, SUBS(R2) > on the flight controller to the solder pads on the DJI Air Unit pin-to-pin. UART1 (T1, R1) is used for OSD and SUBS(R2) is for the internal SBUS receiver signal input of the DJI Air Unit.
Flash(for BlackBox) :
8MB Internal Flash
BetaFlight Camera Control Pad :
Yes (CC pad on the front)
Power Input :
3-6S LiPo. The flight controller is powered through the G and V wires of the 8-pin cable bundle or the G, V pads on the bottom of the flight controller.
5V Output :
4 groups of 5V output, three +5V pads, and one BZ+ pad on the front (used for Buzzer). Total current load is 2A.
9V Output :
1 group of 9V output, one +9V pad on the front. Total current load is 3A.
3.3V Output :
Supported. There is a soldering pad named "3V3" on the front upper part of the flight controller. Designed for 3.3V input receivers. Current load up to 500mA.
4.5V Output :
Supported. Designed for radio receivers and GPS modules even when powered through the FC USB port. Current load up to 1A.
ESC Signal Pads :
At the bottom with M1 - M4 cables or solder pads.
UART :
6 sets (UART1, UART2, UART3, UART4 (dedicated for Bluetooth connection)), UART5 (dedicated for ESC telemetry), UART6
ESC Telemetry UART :
UART R5 (UART5)
LED Pad :
Supported. On the front bottom are 5V, G, and LED pads. Used for WS2812 LEDs controlled by Betaflight software.
Buzzer :
5V pads used for Buzzer, BZ+ and BZ-
BOOT Button :
Supported. Hold the BOOT button and turn on the FC at the same time to force the FC into DFU mode; this is for flashing the firmware if the FC is corrupted.
Supported Flight Controller Firmware :
