Holybro Kakute H7 V1.5 Stack - H743 FC + Tekko32 F4 Metal 65A ESC (30x30)

Specifications

• Flight Controller (Kakute H7 V1.5):

  • MCU: STM32H743 (480MHz).

  • Gyro: ICM-42688-P (Low Noise, V1.5 Exclusive).

  • Barometer: SPA06 (High Precision).

  • Blackbox: MicroSD Card Slot (Unlimited Logging).

  • Connectivity: Bluetooth + USB-C.

  • OSD: AT7456E (Analogue) + UART (Digital).

• ESC (Tekko32 F4 Metal):

  • Current: 65A Continuous / 75A Burst.

  • MCU: F4 Core @ 150MHz (Faster than standard F3/F0 ESCs).

  • PWM: Up to 96kHz (Default) for ultra-smooth flight.

  • Mosfets: Metal Case (High Thermal Efficiency).

  • Mounting: 30.5mm x 30.5mm (M4 holes with M3 grommets).

Compatibility & Platform Support

• Cinematic X8: Native Support. The FC has dual ESC ports, allowing you to plug in two 4-in-1 ESCs easily for an Octocopter build.

• DJI O3 / Vista: Plug-and-Play. Dedicated 9V 3A regulator ensures your HD system gets clean power.

• Firmware: Betaflight (Target: KAKUTEH7), INAV, ArduPilot.

Key Applications & Projects

• Professional Cinelifter: The X8 support and Metal ESCs make it the #1 choice for lifting RED/Cinema cameras.

• Long Range Mountain Surfing: Reliability of the H7 processor + Barometer + GPS support gives peace of mind miles away.

• Spec Racing: The F4 ESC MCU ensures zero-latency motor response.

Virtual Technician: Wiring & Safety ⚠️

• Capacitor: The kit includes a 1000uF 35V Capacitor. You MUST install this for 6S setups to prevent voltage spikes from damaging the sensitive H7 gyro.

• Gyro Version: This is the V1.5 with ICM-42688-P. Ensure you are using Betaflight 4.3 or newer (4.5 recommended) for proper driver support.

• Bluetooth: The Bluetooth module automatically turns OFF when you arm the drone to prevent interference with your control link.

Accessories

• Included in the Package:

  • 1 x Kakute H7 V1.5 Flight Controller

  • 1 x Tekko32 F4 Metal 65A 4-in-1 ESC

  • 1 x Electrolytic Capacitor (1000uF 35V)

  • 1 x JST-SH 8-pin Cable (FC to ESC)

  • 1 x JST-SH 6-pin Cable (DJI Air Unit)

  • 1 x Set of M3 Silicon Grommets

Frequently Asked Questions (FAQ)

1. What is the difference between V1.3 and V1.5? V1.5 uses the newer ICM-42688-P Gyro and SPA06 Barometer, as the older MPU6000 chips are discontinued. V1.5 requires newer Betaflight firmware (4.3+).

2. Why is the ESC called "Metal"? It uses Metal-Cased MOSFETs instead of standard plastic ones. This allows heat to dissipate much faster, keeping the ESC cool under heavy load.

3. Does it support 8 motors (X8)? Yes! It has two ESC ports (M1-M4 and M5-M8), making it one of the easiest stacks to wire for an X8 Octocopter.

4. Can I use the SpeedyBee App? Yes, the onboard ESP32 chip allows full wireless configuration via the SpeedyBee App.

5. Does it work with ArduPilot? Yes, the Kakute H7 is fully supported by ArduPilot for autonomous missions.

6. What is the continuous current rating? 65A per channel, with bursts up to 75A.

7. Is the capacitor necessary? Yes. On a high-performance stack like this, the 1000uF capacitor is critical to protect the H7 gyro from electrical noise.

8. Does it support DShot1200? Yes, the F4 MCU on the ESC supports DShot1200 and PWM frequencies up to 96kHz.

9. Can I power a DJI O3 Air Unit? Yes, the 9V 3A BEC is specifically designed for high-power HD VTXs.

10. Does Bluetooth interfere with my radio? No, the FC automatically disables Bluetooth as soon as you arm the drone.

11. What mounting size is it? Standard 30.5mm x 30.5mm.

12. How much Blackbox storage does it have? It has a MicroSD Card Slot, so storage is virtually unlimited depending on your card size.

13. Is it waterproof? No, but the metal ESC casing offers slightly better physical protection than bare chips.

14. What firmware target should I use? Betaflight Target: KAKUTEH7.

15. Does it have a barometer? Yes, the high-precision SPA06 barometer.

16. Can I use 8S batteries? The FC supports up to 8S, but the ESC is rated for 4S-6S. Do not exceed 6S with this specific bundle.

17. Why does my gyro not work in Betaflight 4.2? The ICM-42688-P gyro in V1.5 is only supported in Betaflight 4.3 and newer.

18. Does it include the DJI cable? Yes, a plug-and-play cable for the Air Unit is included.

19. What is the weight of the stack? The FC is ~8g and the ESC is ~15.8g.

20. Is the USB port Type-C? Yes, robust Type-C connector.
