Holybro Kakute F4 V2.3 Flight Controller with OSD and BMP280 Barometer

The Holybro Kakute F4 V2.3 is the next generation of this popular flight controller. This latest update (V2.3), brings support for the DJI FPV system. The FC can be connected directly to the DJI Air Unit without any soldering (or to the Caddx Vista soldering required), for a neat and simple installation. Not only does the HDV FC provides stable power to the DJI Air Unit, it also sends flight information for display in the DJI FPV goggles. 

At the heart of this flight controller is the powerful F4 STM32F405RGT6 32-bit processor for extra processing speed and the low noise MPU6000 (SPI) IMU gyro/accelerometer which outputs sensor readings at 32Khz. There is an onboard blackbox with 128MB Dataflash chip for all your data logging needs and a barometer sensor to unlock altitude hold mode. Input voltage is 7V to 42V which allows the board to be powered directly from a 6S battery pack. The FC also has a filtered voltage output of 5V 1A and 3.3V 200mA to power peripherals such as GPS, RX, FPV camera or LED strips. There is also a regulator that outputs 9V for the DJI VTX.

The FC supports Betaflight (pre-loaded)/ Cleanflight and it has dedicated bootloader button which makes firmware flashing a breeze. It also supports BLHeli pass through for easy ESC upgrade and configuration. The OSD interface is highly customizable and can be setup and fine tuned to your personal requirements.

The latest version of the Kakute F4 with support for DJI FPV, BetaFlight OSD, barometer and blackbox is one of the best low profile flight controllers available today for your racing drone.

New V2.3 Features:

• Plug and play connection with the DJI Air Unit / compatible with the Caddx Vista Air Unit
• Two extra UART Ports
• UART4 port to for serial camera like the runcam split. (This is not the same as Betaflight Camera Control, which runs of the OSD menu for cameras like the swift, monster).
• UART5 port for ESC telemetry support (for BLheli32 and KISS)
• Through-hole solder pads instead of flat pads for more secure soldering especially for beginners.
• Barometer sensor on board allows altitude hold mode.
• Dedicated I2C pads to connect extra peripherals (like an external compass)

Features:

• STM32F405RGT6 32-bit processor 
• Supports Betaflight and Cleanflight
• High-performance / low-noise IMU. MPU6000 with 6-axis gyro and accelerometer.
• 128MB Dataflash chip for Blackbox logging
• Betaflight OSD. Change PIDs, adjust common configuration parameters, and change video transmitter channel and power level, all using your transmitter sticks and goggles
• Ready for autonomous flight: Integrated BMP280 barometer and SCL/SDA for use with external GPS/magnetometer units.
• Dedicated bootloader button for easy firmware flashing
• Separate USB VCP driver
• Micro USB connector for programming 
• Input voltage 7v to 42v. Power the board directly from the flight pack, up to 6S (on “B+” pad only)
• Automatic voltage monitoring. No need to run a separate vBat wire for voltage monitoring; the Kakute F4 V2 monitors voltage directly from the battery power lead
• On-board regulators output 5v at up to 1.0 amps and 3.3v at up to 200 mA to power peripherals such as receiver, video transmitter, FPV camera, or LED strip
