IMU(Gyro)

BMI270

USB Port Type

Type-C

Barometer

Built-in

OSD Chip

AT7456E chip

BLE Bluetooth

Supported. Used for Flight Controller configuration

DJI Air Unit Connection Way

Two ways supported: 6-pin connector or direct soldering.

Blackbox MicroSD Card Slot

*Betaflight firmware requires the type of the microSD card to be

either Standard (SDSC) or High capacity (SDHC).so extended

capacity cards (SDXC) are not supported(Many high-speed U3

cards are SDXC). Also the card MUST be formatted with the

FAT16 or FAT32 (recommended) filesystems. So. you could

use any SD card less than 32GB. but the Betaflight can only

recognize 4GB maximum. We suggest you use this

3rd party formatting tooland choose 'Overwrite format' then format

your card.

BetaFlight Camera Control Pad

Yes(CC pad on the front side)

Current Sensor Input

Supported. For SpeedyBee BLS 50A ESC. please set scale = 386 and Offset = 0.

Power Input

3S - 6S Lipo(Through G. BAT pins/pads from the 8-pin connector or 8-pads on the bottom side)

5V Output

9 groups of 5V output. four +5V pads and 1 BZ+ pad( used for Buzzer) on front side.

and 4x LED 5V pads. The total current load is 2A.

9V Output

2 groups of 9V output. one +9V pad on front side and other included in a connector

on bottom side. The total current load is 2A.

3.3V Output

Supported. Designed for 3.3V-input receivers. Up to 500mA current load.

4.5V Output

Supported. Designed for receiver and GPS module even when the FC is powered

through the USB port. Up to 1A current load.

ESC Signal

M1 - M4 on bottom side and M5-M8 on front side.

UART

5 sets(UART1. UART2. UART3. UART4(For ESC Telemetry). UART6)

ESC Telemetry UART

R4(UART4)

I2C

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.
