Description

The Holybro Kakute H7 V2 Flight Controller is engineered for high-performance FPV and autonomous drone applications. It builds upon the F7 series with an upgraded STM32H743 microcontroller, a high-sensitivity BMI270 IMU mounted on vibration-damping foam, and a comprehensive suite of connectivity options including 6 UARTs with hardware inversion. The board is designed for clean integration, featuring dedicated pads for LED, buzzer, and I2C peripherals like GPS modules.

Power management is robust, with a wide 7-42V input voltage range supporting 4S to 10S LiPo batteries and separate 5V and 9V BEC outputs. The integrated AT7456E OSD chip allows for real-time telemetry overlay directly in FPV feeds. Its layout is optimized for easy soldering and a clean build, with dual ESC connectors simplifying wiring for complex multirotor setups.

Key Features

  • High-performance STM32H743 MCU operating at 480 MHz for maximum processing headroom.
  • Integrated ESP32-C3 Bluetooth module enables wireless Betaflight tuning and telemetry via smartphone.
  • Dedicated 9V VTX ON/OFF Pit Switch controllable via a transmitter channel for safe ground operation.
  • Dual plug-and-play 4-in-1 ESC ports facilitate easy connection for 8-motor octocopter configurations.
  • 128 MB of onboard flash memory provides ample storage for detailed blackbox flight logs.
  • Wide input voltage range (7-42V) supports high-voltage setups from 4S to 10S LiPo batteries.
  • High-sensitivity BMI270 IMU with 6-axis gyro/accelerometer, isolated for precise flight data.
  • Six UART ports with hardware inversion support extensive peripherals like GPS, telemetry, and VTX control.

Applications

  • High-performance 5-inch and 7-inch FPV racing drones requiring fast processor response.
  • Long-range autonomous mapping or inspection drones utilizing its 6 UARTs for GPS and telemetry.
  • Cinematic FPV builds using DJI/CaddxFPV HD digital systems or high-power analog VTXs.
  • Advanced octocopter or heavy-lift platforms leveraging the dual ESC ports for 8-motor control.
  • Betaflight-based freestyle quads where wireless Bluetooth tuning via SpeedyBee app is preferred.

Frequently Asked Questions

How do I enable and use the VTX ON/OFF Pit Switch on the Kakute H7 V2?

The VTX ON/OFF Pit Switch is controlled via a transmitter channel. In Betaflight Configurator, assign a switch to the 'USER1' mode in the Modes tab. When activated, this mode will cut power to the onboard 9V VTX output, useful for preventing interference on the ground. Note: Do not enable this feature if using a DJI FPV Remote Controller for control link.

What is the function of the onboard Bluetooth chip and how do I connect?

The integrated ESP32-C3 Bluetooth chip allows wireless connection to the SpeedyBee mobile app for tuning Betaflight PIDs, rates, and OSD settings without a USB cable. The Bluetooth automatically disables when the drone is armed for safety and re-enables upon disarming. Ensure your phone's Bluetooth is on and select the flight controller within the SpeedyBee app to connect.

What is the maximum input voltage and motor support for this flight controller?

The Kakute H7 V2 supports a wide input voltage range of 7V to 42V, making it compatible with battery packs from 2S up to 10S LiPo. It features dual plug-and-play 4-in-1 ESC ports, allowing it to control up to 8 individual motors, which is ideal for octocopter or complex heavy-lift drone configurations.

Which firmware is compatible with the Holybro Kakute H7 V2?

This flight controller is primarily designed for Betaflight firmware, which supports all its core features like the OSD, Bluetooth telemetry, and the pit switch. It is also compatible with Cleanflight and supports BLHeli pass-through for configuring connected ESCs directly via the Betaflight configurator interface.
