Description

Engineered for demanding FPV and autonomous flight applications, the Kakute H7 Mini leverages the computational power of the STM32H743 microcontroller to handle complex flight algorithms with minimal latency. Its robust power design eliminates the need for external regulators, accepting a direct 2S to 6S battery connection while providing clean 5V power for peripherals.

The board integrates a dedicated AT7456E chip for crisp, low-latency OSD generation, allowing pilots to view critical telemetry data directly in their FPV feed. With six UART serial ports, it offers extensive expansion capabilities for GPS modules, digital video systems like DJI Air Unit or Walksnail, telemetry radios, and other serial-based accessories, making it a versatile core for complex builds.

Key Features

  • High-performance STM32H743 MCU with double-precision FPU for advanced flight control algorithms.
  • Dedicated AT7456E OSD processor ensures stable, flicker-free telemetry overlay.
  • 128 MByte onboard data flash for extensive blackbox logging and configuration storage.
  • Robust 7-26V input range with built-in 5V/2A BEC for powering FPV cameras, VTXs, and receivers.
  • Nine PWM outputs support eight motors/servos plus a dedicated WS2812 addressable LED signal.
  • Six full-featured UARTs provide ample connectivity for GPS, telemetry, SmartAudio/Tramp, and digital VTX control.
  • Integrated high-performance BMI270 IMU and BMP280 barometer for precise attitude and altitude hold.
  • USB-C port for reliable firmware updates and Betaflight/ArduPilot configuration.

Applications

  • High-performance 5-inch and 7-inch FPV racing drones requiring fast processor response for advanced Betaflight filtering.
  • Long-range fixed-wing or VTOL aircraft utilizing ArduPilot or iNAV for autonomous navigation and mission planning.
  • Cinewhoop and freestyle quadcopters where a compact, powerful FC is needed to manage high-torque motors and digital HD FPV systems.
  • Advanced DIY drone projects integrating multiple peripherals like GPS, telemetry, LED lighting, and gimbal control.

Frequently Asked Questions

What is the input voltage range for the Kakute H7 Mini FC?

The Kakute H7 Mini accepts a wide input range of 7V to 26V directly from your LiPo battery, making it compatible with 2S, 3S, 4S, 5S, and 6S battery packs without requiring an external voltage regulator.

How many UARTs are available, and what can I connect to them?

This flight controller provides six full UARTs. These can be used to connect a GPS module for navigation, a digital VTX (like DJI or Walksnail) for control, telemetry radios (ExpressLRS, Crossfire), SmartAudio/Tramp for analog VTX control, and other serial peripherals simultaneously.

Does this flight controller have a built-in OSD?

Yes, it features a dedicated AT7456E video processor chip for on-screen display (OSD). This allows you to overlay critical telemetry data such as battery voltage, flight mode, RSSI, and artificial horizon directly onto your FPV video feed.

What firmware is compatible with the Kakute H7 Mini?

The Kakute H7 Mini is fully compatible with Betaflight, ArduPilot (including Rover and Plane), and iNAV firmware. Its STM32H743 processor and ample memory support the latest features and filtering algorithms in these platforms.
