Kakute F4 AIO
Flight Controller
The Holybro Kakute F4 All-In-One flight controller makes it easy to build your multirotor. It integrates flight controller (FC), power distribution board (PDB), and on-screen display (OSD) in one. The Kakute F4 AIO's layout makes it easy to wire up the other components of the multirotor while keeping the build neat and tidy.

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.

2 oz. copper PCB allows up to 120A maximum continuous current.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 AIO 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.Supports BLHeli pass-through for easy ESC upgrade and configuration.

If you chose the option "full chip erase" when you were reflashing the firmware, which leads to a smart port that can not work properly, please input the following command into the CLI.
set sport_halfduplex = OFF

There is an issue (interference between the OSD and blackbox) on those kakueF4 AIOs we have shipped in June. We have managed to fix this bug on the boards shipped since July and submitted the PR to the Betaflight. The official Betaflight after V3.1.7 will fix this bug. Those who found there is interference between the OSD and the blackbox on his/her Kakute please reflash the firmware using the hex file offered here
