Holybro Kakute H7 V1.5 (ICM-42688-P) Flight Controller without Bluetooth
by Holybro

The Holybro Kakute H7 V1.5 Flight Controller without Bluetooth (SKU: 11091C) is a high-performance 30.5x30.5mm autopilot powered by a 32-bit STM32H743 processor running at 480MHz. Designed for pilots and commercial operators who do not require wireless mobile app tuning or prefer a board layout without active RF broadcast components, this variant omits the onboard ESP32 Bluetooth module, freeing UART2 entirely for external peripherals.

Updated in revision V1.5 with the low-noise InvenSense ICM-42688-P IMU and an SPA06 barometer, the Kakute H7 non-Bluetooth edition provides processing capability for fast loop rates and advanced digital filtering. It features dual 4-in-1 ESC ports for octocopter (X8) builds, a plug-and-play 9V BEC port for DJI HD air units, a full MicroSD card slot for Blackbox logging, and a wide 3S to 8S (7V–42V) power input range.

Key Features

• Non-Bluetooth Variant (SKU: 11091C): Omits the onboard ESP32 wireless chip, eliminating potential local RF telemetry emissions and freeing UART2 for dedicated hardware peripherals.

• STM32H743 Processor @ 480MHz: High-speed 32-bit Cortex-M7 MCU provides computational headroom for complex filtering, fast loop rates, and INAV/ArduPilot/PX4 tasks.

• Upgraded ICM-42688-P IMU & SPA06 Baro: Features a low-noise 6-axis gyro/accelerometer with underfill epoxy mechanical reinforcement and onboard barometric altitude sensing.

• Dual 4-in-1 ESC Ports (X8 Support): Twin 8-pin JST-SH ports simplify wiring to dual ESCs for octocopter and X8 cinematic drone configurations.

• Dedicated Digital HD Port: Integrated 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 Voltage Range: Handles 7V to 42V DC power input with dual onboard BECs (5V/2A and 9V/3A) to power onboard receivers, GPS modules, and cameras.
