Holybro Kakute F4 Flight Controller


In stock

The HolybroKakute F4 flight controller supports important features of Betaflight/Cleanflight, such as OSD and Dshot. The faster F4 processor gives room for future feature development: run all features at the fast 8 kHz PID loop rate, at single-digit CPU utilization! Because of issues with serial inversion, other F4 boards struggle to support protocols such as FrSky SBUS and SmartPort at the same time. The Kakute F4 is designed to support all serial protocols at once.

Holybro Kakute F4  Flight Controller  for DIY FPV Racing Drone


·       Supports Betaflight and Cleanflight.

·       Betaflight OSD. Change PIDs, adjust common configuration parameters, and change video transmitter channel and power level, all using your transmitter sticks and goggles.

·       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.

·       New high-performance / low-noise / high sensitivity IMU. ICM20689 with 6-axis gyro and accelerometer. Can run at up to 32 kHz.

·       Dedicated bootloader button for easy firmware flashing.

·       Low-profile design fits into even very compact frames.

·       Input voltage 7v to 42v. Power the board directly from the flight pack, up to 6S (on “BAT” pad only).

·       Automatic voltage monitoring. No need to run a separate vBat wire for voltage monitoring; the Kakute F4 monitors voltage directly from the battery power lead.

·       Filtered voltage output for clean, noise-free video. On-board regulators output 5v at up to 1.5 amps and 3.3v at up to 200 mA to power peripherals such as receiver, video transmitter, FPV camera, or LED strip.

·       PPM input is shared with UART6 RX pad for simple receiver installation regardless of type.

·       Supports BLHelipass-through for easy ESC upgrade and configuration.


·       MCU: STM32F405RGT6 32-bit processor

·       IMU: ICM20689 (SPI)

·       USB VCP Driver (all UARTs usable simultaneously; USB does not take up a UART)

·       3 hardware UARTS (UART1,3,6)

·       128 Mbit Dataflash chip for Blackbox logging

·       5v Power Out: 1.5 A max

·       3.3v Power Out: 200 mA max

·       Dimensions: 35x25x7mm (Includes USB height)

·       Mounting Holes: Standard 30.5mm square to center of holes 

      ·      Weight: 5g
