Description

The Holybro Kakute F4 V2.4 and Tekko32 F4 ESC stack combines a feature-rich flight controller with a high-current electronic speed controller in a single, optimized unit. The flight controller is built around a powerful STM32F405 processor and includes a dedicated, regulated port for seamless integration with DJI’s O3 Air Unit and CaddxFPV Vista digital HD systems, eliminating the need for external voltage regulators.

The paired Tekko32 F4 4-in-1 ESC utilizes a 3 oz copper PCB and metal-cased MOSFETs to handle up to 65A per motor continuously, with excellent thermal performance for demanding 6S and 8S applications. The design employs separate drive and control circuits to minimize electrical interference, ensuring clean signal processing for the flight controller’s MPU6000 IMU and BMP280 barometer.

Key Features

  • DJI O3/CaddxFPV Vista Integrated: On-board plug-and-play JST port with 9V/3A BEC directly powers HD video transmitters without extra wiring.
  • High-Speed Processing: STM32F405 MCU operates at 150MHz, significantly faster than F3 or F0 chips for complex flight algorithms.
  • Advanced Power Design: Tekko32 ESC features metal-cased MOSFETs and 2068uF capacitance for superior heat dissipation and noise filtering on 2S-8S inputs.
  • Expanded Connectivity: Five UART ports with hardware inversion support easy connection to GPS, telemetry radios, and other serial peripherals.
  • Professional Flight Features: Includes barometer for altitude hold, built-in OSD, data logging to onboard flash, and dedicated LED/buzzer pads.
  • Durable Construction: 3 oz copper PCB on the ESC enhances current carrying capacity and thermal management for long-term reliability.

Applications

  • High-performance 5-inch and 7-inch FPV racing and freestyle drones requiring 6S or 8S power.
  • Long-range and autonomous drone builds utilizing the barometer and multiple UARTs for GPS and telemetry.
  • Digital HD FPV builds specifically designed for the DJI O3 Air Unit or CaddxFPV Vista system.
  • Heavy-lift and cinematic drone platforms needing the robust 65A per motor current handling.

Frequently Asked Questions

Is this stack compatible with the DJI O3 Air Unit?

Yes, the Kakute F4 V2.4 flight controller includes a dedicated plug-and-play JST port with an on-board 9V/3A BEC specifically designed to power and interface with the DJI O3 Air Unit and CaddxFPV Vista systems without requiring any external voltage regulators or complex wiring.

What is the maximum battery voltage this ESC can handle?

The Tekko32 F4 4-in-1 ESC is rated for a battery input range of 2S to 8S LiPo. This corresponds to a nominal voltage range of approximately 7.4V up to 33.6V, making it suitable for high-power 6S and 8S FPV drone applications.

How many UARTs are available for connecting peripherals like GPS?

The Kakute F4 V2.4 provides five dedicated UART ports, all with built-in hardware inversion support. This allows for simultaneous connection of peripherals such as a GPS module, ExpressLRS or Crossfire receiver, HD VTX for smart audio, and telemetry modules without the need for softserial.

What is the mounting hole pattern for this stack?

The combined FC and ESC stack uses a standard 30.5mm x 30.5mm mounting hole pattern. The holes are 4mm in diameter and are intended to be used with the included M3 vibration-damping grommets for isolating the flight controller from frame vibrations.
