The Holybro Kakute F4 All-In-One V2 flight controller makes it easy to build your multirotor. It integrates flight controller (FC), power distribution board (PDB) with current sensor, and on-screen display (OSD) in one. The V2 comes with many improvements over the previous model.

The Holybro Kakute F4 A10 Version 2 is the next generation of this popular flight controller. New features over the original F4 AIO are, additional UART's (UART 4-5), through hole solder pads, BMP280 barometer, low profile and a 12C pad available for certain external sensors.

It still has all the popular features of the original FC such as an OSD (on screen display) and a 120amp PDB (power distribution board) integrated into the same slim package, which makes it very simple and convenient to build a racing drone. At the heart of this flight controller is the powerful F4 STM32F405RGT6 32-bit processor for extra processing speed and the low noise ICM20689 (SPI) IMU gyro/accelerometer which outputs sensor readings at 32Khz. Thanks to the vibration-isolated IMU, soft mounting your flight controller is a thing of the past. There is an onboard blackbox with 128MB Dataflash chip for all your data logging needs and now a Barometer sensor to unlock altitude hold mode. The built in PDB does away with header pins in preference to soldering straight to the board with reinforced, gold plated solder pads. Input voltage is 7V to 42V which allows the board to be powered directly from a 6S battery pack, and the PDB maximum continuous current is 120A. The FC also has a filtered voltage output of 5V 1.5A and 3.3V 200mA to power peripherals such as GPS, RX, FPV camera or LED strips. 5v/3.3v RX selectable.

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

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

New V2 Features:

  • 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)


  • STM32F405RGT6 32-bit processor 
  • New high-performance / low-noise / high sensitivity IMU. ICM20689 with 6-axis gyro and accelerometer. Can run at up to 32 kHz
  • 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
  • Dedicated bootloader button for easy firmware flashing
  • Separate USB VCP driver
  • High quality, gold plated 2 oz. copper PCB allows up to 120A maximum continuous current
  • Soft-mounting built in. The IMU ("gyro") chip on this board is mounted on vibration-isolating foam. This means that there is no need to soft-mount the board itself
  • Micro USB connector for programming 
  • High voltage input, 7 to 42V (up to 6S)
  • Automatic voltage monitoring. No need to run a separate vBat wire for voltage monitoring; the Kakute F4 AIO monitors voltage directly from the battery power lead
  • Filtered voltage output for noise free clean video
  • Supports Betaflight and Cleanflight
  • Supports BLHeli pass-through for easy ESC upgrade and configuration
  • Low-profile design fits into even very compact frames
  • MCU: STM32F405RGT6 32-bit processor
  • IMU: ICM20689 (SPI)
  • Barometer: BMP280
  • USB VCP Driver: Separate from UART's, usable simultaneously with all UART's
  • UART's: 5 (UART 1, 3, 4, 5, 6)
  • Receivers: Supports SBUS, iBus, Spektrum, Crossfire only, PPM and PWM receivers are not supported
  • Logging: 128 Mbit Dataflash chip for Blackbox logging
  • Dimensions: 35 x 43 x 7mm (Inc USB)
  • Mounting Holes: 30.5 x 30.5mm
  • Weight: 7g


  • 1x Flight controller board
  • 3x Spare IMU mounting foam
