- Modern ICM42688-P Gyroscope – Provides excellent vibration resistance and unprecedented flight stabilization precision in all conditions.
- Rich UART Connectivity – Features up to 6 full UART ports, allowing for the simultaneous connection of GPS, CRSF/ELRS systems, DJI OSD, and telemetry.
- Compact Mini Format – Thanks to the 25x 30 x 20 mm dimesnions and 20 x 20mm mounting hole spacing, it fits perfectly into small FPV wing fuselages.
FAQ Holybro Kakute F405 Wing Mini Flight Controller
No. The specified variant is Kakute F405-Wing Mini / None, which means it is a kit without a GPS module. A GPS can be purchased separately if the project requires navigation, return-to-home (RTH), or autopilot functionality.
Yes. The manufacturer specifies support for the Kakute F405 Wing Mini target in INAV starting from version 7.1.2 and newer.
No. This is a flight controller with a separate power board and ESC power pads. Electronic Speed Controllers (ESCs) must be selected and connected separately.
Who is the Holybro Kakute F405 Wing Mini Flight Controller ideal for?
The Holybro Kakute F405 Wing Mini is an ideal choice for advanced pilots and ambitious hobbyists who are building smaller FPV wings and need a lightweight yet feature-rich controller. Integrated systems facilitate installation in tight fuselages. However, this product is not recommended for individuals looking for simple, "plug-and-play" solutions that require no soldering or software configuration, nor for giant-scale models requiring a massive number of servo outputs, where full-sized controllers would be a better fit.
