Specications
Product Name SpeedyBee F405 V3 30x30 Flight Controller
MCU STM32F405
IMU(Gyro) BMI270
USB Port Type Type-C
Barometer Built-in
OSD Chip AT7456E chip
BLE Bluetooth
Supported. Used to connect with the SpeedyBee App for flight controller and ESC parameter
configuration. Please make sure the MSP switch on UART 4 is turned on and set to a baud
rate of 115200, otherwise Bluetoothfunctionality will not be available.
WIFI Not supported
DJI Air Unit Connection Way Two ways supported: 6-pin connector or direct soldering.
6-pin DJI Air Unit Plug
Supported. Completely compatible with DJI O3/RunCam Link/Caddx Vista/DJI Air Unit V1, no
wire is needed to be changed.
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 tool and
choose 'Overwrite format' then format your card. Also check out
here for the recommended SD
cards or buy the
tested cards from our store.
Current Sensor Input Supported. For SpeedyBee BLS 60A ESC, please set scale = 400 and Offset = 0.
Power Input
3-6S LiPo. The flight controller is powered through the G, V wires of the 8pin cable or G, V pads
from the bottom side of the flight controller.
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
6 sets(UART1, UART2, UART3, UART4(Dedicated for Bluetooth connection)),
UART5(Dedicated for ESC telemetry),UART6
ESC Telemetry UART R5
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.
Smart Port / F.Port Not supported
Supported Flight Controller Firmware
BetaFlight(Default), INAV (INAV firmware can only use Multishot (recommended) and
OneShot125. Please note that DShot is not supported.)
