Holybro Kakute H7 Flight Controller with Bluetooth & Barometer

Holybro Kakute H7 Flight Controller with Bluetooth & Barometer

Product description

The Holybro Kakute H7 Flight Controller is a modern, premium FC for high-performance FPV drones, combining extreme processing power, built-in Bluetooth, HD-VTX support, and a well-thought-out layout in a compact 30x30 design. Designed for demanding freestyle, racing, and cinematic builds, the Kakute H7 offers everything modern FPV pilots need—and probably a little more, just in case you decide to launch a small space program on a whim.

At its core is an ultra-fast 480 MHz STM32H743 processor that effortlessly handles even complex filter calculations, high-frequency gyro loops, and modern Betaflight features. This is supported by high-quality sensors such as the ICM-42688-P gyro and an integrated barometer for precise altitude information.

A special highlight is the integrated Bluetooth module (ESP32-C3), which allows you to configure and tune the flight controller wirelessly via the SpeedyBee app on Android or iOS. No USB cable, no laptop at the field, no ritualized cursing over hard-to-reach USB ports in the frame. Humankind discovered fire; FPV discovered Bluetooth.

The Kakute H7 is also fully DJI HD Ready and offers a convenient plug-and-play connection for digital systems such as the DJI Air Unit or Caddx Vista, including an integrated 9V BEC. At the same time, full compatibility with analog VTX systems is maintained.

Thanks to 6 UARTs, a MicroSD black box, OSD, I2C support, and dual 4-in-1 ESC connectors, the flight controller is also suitable for complex setups, including X8 octocopter configurations.
