Description

The Kakute F4 V2.4 stack combines a feature-rich flight controller with a robust 4-in-1 ESC, designed for demanding 5-inch and 6-inch FPV builds. The flight controller’s separate drive and control circuits minimize electrical interference, ensuring clean signal processing for precise flight control. Its 5 dedicated UARTs with built-in inversion support extensive peripherals like GPS, telemetry radios, and LED controllers.

The integrated Tekko32 F4 ESC utilizes BLHeli_32 firmware, offering smooth motor control with support for DShot1200, ESC telemetry, and PWM frequencies from 16kHz to 96kHz. The included 1000uF 35V capacitor is critical for stabilizing voltage spikes in high-performance 6S setups, protecting the sensitive electronics from noise and ensuring reliable operation.

Key Features

  • High-Speed Processing: STM32F405 150MHz MCU provides ample headroom for complex flight algorithms and filtering.
  • Digital HD Ready: Onboard 9V/3A BEC and dedicated JST-SH port for seamless integration with DJI O3 Air Unit and CaddxFPV Vista systems.
  • Robust Power Delivery: Tekko32 F4 ESC handles 50A continuous (60A burst) per motor, suitable for high-torque 2207-2507 motors on 6S.
  • Advanced Telemetry: Onboard analog current sensor and ESC telemetry support provide real-time power consumption data.
  • Durable Construction: High-quality PCB with conformal coating and separate power/control circuits for enhanced electrical noise immunity.
  • Comprehensive Connectivity: 5x UARTs, I2C port, dedicated LED/buzzer pads, and an integrated OSD for clean builds.
  • Optimized Form Factor: 48x37mm footprint with 30.5x30.5mm M4 mounting pattern (M3 grommets included) for standard frame compatibility.

Applications

  • 5-inch and 6-inch high-performance FPV racing drones requiring integrated FC/ESC stacks.
  • Freestyle builds utilizing DJI O3 Air Unit or CaddxFPV Vista for digital HD FPV.
  • Long-range or autonomous drone platforms leveraging the onboard barometer and multiple UARTs for GPS/telemetry.
  • Competition-level quads where low-latency DShot1200 and high-current ESC performance are critical.
