FlyingRC F4Wing Mini MK1 F405 Fixed-wing Flight Controller
An ultra-small fixed-wing autopilot board. It is the central controller for a small plane: it reads sensors, runs ArduPilot/INAV-style flight firmware, outputs servo/PWM control, and provides connectors for receiver and HD video equipment.
Best used for
- Small and micro fixed-wing aircraft where board size and weight matter.
- Builders who want ArduPlane/INAV capability in a compact airframe.
- HD digital video builds using DJI HD, Walksnail HD, OpenIPC, or similar HD OSD workflows.
Key features
- STM32F405RGT6 MCU with BMI270 IMU on current units released from May 25, 2026; earlier units used ICM42688P/ICM42605.
- SPL06/SPA06 barometer, with dual independent sensor LDOs to improve sensor power stability.
- 3 UARTs plus SBUS, 6 PWM outputs, I2C, Type-C USB, HD VTX plug-in, and ELRS receiver plug-in support.
- Supports AP, Betaflight, and INAV; ArduPlane is recommended for fixed-wing use.
Setup / wiring notes
- Use the SH1.0 2P connector only for battery voltage detection and HD VTX direct-power input, not as the flight-controller power input.
- For fixed-wing aircraft, start from ArduPlane wiring examples and check UART/SERIAL mapping carefully.
- Use USB-C for configuration; mobile ground-station setup is possible with a USB-C to USB-C cable.
Check before use
- Analog OSD is not supported on this board.
- Because there is no onboard BEC, plan a clean 5 V supply for the flight controller.
