Description

The Kakute F4 V2.4 is engineered as a versatile flight controller core for modern FPV and cinematic drone builds. Its STM32F405 processor, coupled with the MPU6000 gyro/accelerometer, delivers the computational headroom needed for complex Betaflight filtering and advanced flight modes. The inclusion of a BMP280 barometer enables altitude hold and autonomous flight functions in compatible firmware like ArduPilot or iNav.

Power management is robust, handling input voltages from 2S to 8S LiPo batteries. The board features dedicated, regulated 9V/3A and 5V/2A BEC outputs, eliminating the need for external regulators when powering HD video transmitters like the DJI O3 Air Unit or analog VTXs. The compact 37x37mm mounting pattern and lightweight 7g design ensure compatibility with a wide range of frame sizes without compromising on payload capacity.

Key Features

  • High-Performance Processing: STM32F405 MCU provides ample processing power for Betaflight, Cleanflight, and other open-source flight firmware.
  • Integrated HD System Support: Onboard 9V/3A BEC and dedicated JST-SH connector offer plug-and-play power and data for DJI O3 and CaddxFPV Vista digital HD systems.
  • Comprehensive Sensor Suite: MPU6000 IMU and BMP280 barometer deliver stable flight characteristics and enable altitude-hold and return-to-home functions.
  • Extensive Connectivity: Five UART ports with hardware inversion support GPS modules, telemetry radios, and other serial peripherals without signal converters.
  • Advanced Power & Logging: Built-in current sensor, wide-input BEC, and 128 Mbit dataflash chip allow for precise power monitoring and detailed blackbox flight analysis.
  • Optimized Layout: Clearly labeled solder pads and connectors simplify wiring, while the 37x37mm form factor fits standard FPV stack configurations.

Applications

  • 5-inch and 7-inch long-range FPV drones requiring stable flight control and HD video transmission.
  • Freestyle and racing quadcopters where low latency, precise control, and blackbox logging are critical.
  • Aerial photography platforms utilizing GPS for position hold, waypoint navigation, and return-to-home.
  • Builds integrating digital HD FPV systems (DJI O3 Air Unit, CaddxFPV Vista) for a clean, solder-free video link setup.
  • Heavy-lift or experimental multirotor projects needing robust 8S power handling and extensive peripheral connectivity.

Frequently Asked Questions

What is the input voltage range for the Kakute F4 V2.4?

The Kakute F4 V2.4 supports a wide input voltage range from 2S (7.4V) to 8S (33.6V) LiPo batteries. Its onboard power regulation provides stable 9V/3A and 5V/2A outputs for peripherals, eliminating the need for external BECs in most builds.

Does this flight controller support the DJI O3 Air Unit natively?

Yes, it features a dedicated plug-and-play JST-SH connector and an onboard 9V/3A BEC specifically designed to power and interface with the DJI O3 Air Unit and CaddxFPV Vista digital HD systems. This provides a clean, solder-free installation for the video link.

How many UARTs are available and what are they used for?

The board provides five dedicated UART ports (serial communication interfaces). These are typically used for connecting a GPS module (for navigation), a telemetry radio (for ground station data), a receiver (for RC link), and other serial peripherals like LED strips or rangefinders, all without requiring external signal inverters.
