Specification
Product Name - SpeedyBee F405 V3 30x30 Flight Controller - MCU - STM32F405
IMU (gyro) - BMI 270
USB port type - Type C
Barometer - Built-in
OSD chip - AT7456E chip

DJI air unit connection type
Two types are supported: 6-pin connector or direct soldering.
Blackbox MicroSD card slot
*The microSD card type must be standard (SDSC) or high capacity (SDHC) to use the Betaflight firmware, so extended capacity cards (SDXC) are not supported (many high-speed U3 cards are SDXC). Also, the card MUST be formatted with FAT16 or FAT32 (recommended) file system. So, you could use any SD card smaller than 32GB, but Betaflight can only recognize 4GB. We suggest you use this third-party formatting tool and choose "Overwrite Format" then format the card. Also check out the recommended SD cards here or buy tested cards in our store.
BetaFlight camera control panel
Yes (CC pad on front)
Current sensor input
Supported. For SpeedyBee BLS 50A ESC, please set Scale = 386 and Offset = 0.
Power supply : 3S - 6S Lipo (via G, BAT pins/pads from 8-pin connector or 8 pads on bottom side)
5V output
9 groups with 5V output, four +5V pads and 1 BZ+ pad (used for buzzer) on the front, as well as 4 LED 5V pads. The total current load is 2A.
9V output
2 groups of 9V outputs, one +9V pad on the front and one included in the connector on the bottom. The total current load is 2A.
3.3V output
Supported. Designed for 3.3V input receivers. Current load up to 500 mA.
4.5V output
Supported. Designed for receiver and GPS module even if FC is powered via USB port. Up to 1A current load.
ESC signal
M1 - M4 on the underside and M5-M8 on the front.
UART
5 sets (UART1, UART2, UART3, UART4 (for ESC telemetry), UART6)
ESC telemetry UART
R4 (UART4)
I2C
Supported. SDA and SCL pads on the front. Used for magnetometer, sonar, etc.
Traditional Betaflight LED pad
Supported. 5V, G and LED pads at the bottom of the front. Uses WS2812 LED controlled by Betaflight firmware.
Summer
BZ+ and BZ- pad used for 5V buzzer
BOOT button : [A]. Press and hold the BOOT button and mode on FC to boot into FC switched DFU. This is for flashing the firmware when the FC is locked.
[B]. When the FC is powered on and in standby, the BOOT button can be used to control the LED strips connected to the back side of the LED1-LED4 connectors. Then press the BOOT button briefly to switch the LED display mode. Hold the BOOT button to switch between SpeedyBee-LED and BF-LED mode. BF-LED enables all LED1-LED4 strips to be controlled by Betaflight firmware.
RSSI Input : Named as RS on the front.
SmartPort : Use UART TX pad for SmartPort function.
