March 25th, 2024 BeiJing Time Specifications: Product Name:FLASH HOBBY F405 30.5x30.5 Flight Controller MCU:STM32F405 IMU(Gyro):ICM42688 USB Port Type:Type-C Barometer:BMP280 OSD Chip:BetaFlight OSD w/ AT7456E chip DJI Air Unit Connection Way:Two ways supported: 6-pin connector or direct soldering. 6-pin DJI Plug:Supported. Completely compatible with DJI O3/RunCam Link/Caddx Vista/DJI Air Unit V1, no wire is needed to be changed. Black box:16M Black Box Current Sensor Input:Supported. For 50A ESC, please set scale = 180 and Ofset = 0. Power Input:3S - 6S Lipo(Through ESC 8-PIN connector) 5V BEC Output:5 grous 5V output,the total current load is 3A 9V Output:3 groups 9V output,the total current load is 2.5A 3.3V Output:1 group 3.3V output,maxmum current is 300mA ESC Signal:M1 - M4 UART:6 sets(UART2 UART5, UART3), UART6(Dedicated for SBUS), UART4(Dedicated for ESC telemetry),UART1 (Dedicated for VTX data setting) Sbs:Debugging to UART6 Channel ESC Telemetry:UART R4(UART4) I2C:Supported. SDA & SCL pads on front side. Used for magnetometer. LED Pad:Supported. LED,5V, and GND pads on bottom of the front side. Used for WS2812 LED controlled by Betaflight firmware. Buzzer:supported,5V,BZ pads 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 theLEDstrips connected to LED1-LED4 connectors onthebottom side. By default, short-press the BOOTbuttonto cycle the LED displaying mode. Long-press theBOOT button to switch between SpeedyBee-LEDmode and BF-LED mode. Under BF-LEDmode, all theLED1-LED4 strips will be controlled by Betaflight firmware.
