Holybro Kakute H7 V1.5 (ICM-42688-P) Flight Controller
by Holybro

The Holybro Kakute H7 V1.5 Flight Controller is a feature-packed 30.5x30.5mm autopilot powered by a 32-bit STM32H743 processor running at 480MHz. Updated in revision V1.5 with the low-noise InvenSense ICM-42688-P IMU sensor and an SPA06 barometer, the Kakute H7 provides ultra-fast processing capability and precise sensor telemetry for FPV freestyle quads, long-range cinematic drones, and X8 octocopters.

Featuring integrated ESP32-C3 wireless Bluetooth connectivity, pilots can perform Betaflight configuration and PID tuning on iOS and Android mobile devices using the SpeedyBee App. The flight controller includes dual 4-in-1 ESC ports for octocopter builds, a dedicated plug-and-play port with a 9V BEC for DJI HD and analog video transmitters, a full MicroSD card slot for unlimited Blackbox logging, and a wide 3S to 8S (7V–42V) power input range.

Key Features

• STM32H743 Processor @ 480MHz: High-performance 32-bit Cortex-M7 core delivers processing power for high loop rates, advanced filters, and multi-protocol telemetry.

• Upgraded ICM-42688-P IMU & SPA06 Barometer: Low-noise 6-axis gyro/accelerometer architecture combined with an onboard barometer for accurate altitude holding.

• Integrated Wireless Bluetooth (ESP32-C3): Configure Betaflight wirelessly via the SpeedyBee mobile app on Android or iOS without connecting a USB cable.

• Dual 4-in-1 ESC Ports (X8 Support): Includes two 8-pin JST-SH ports for simple plug-and-play wiring to dual ESCs on X8 octocopter configurations.

• Plug-and-Play Digital HD Port: Dedicated 9V/3A BEC and 6-pin connector provide clean power and signal for DJI O3, Caddx Vista, and HDZero air units.

• Wide 3S to 8S Input Range: Accepts 7V to 42V DC input with onboard 5V/2A and 9V/3A BEC regulators for peripheral electronics.
