Flight Controller F405-WMN
Description
1. Product Summary
1.1. Product Description
The Matek Systems F405-WMN is a high-performance and compact flight controller designed for fixed-wing, VTOL, and professional FPV aircraft. It integrates the STM32F405RGT6 MCU running at 168 MHz, precision ICM42688-P IMU, and SPL06-001 barometer. The controller features an integrated PDB with a built-in 90 A current sensor, dual camera input, and powerful 5 A servo BEC output. Supporting ArduPilot and INAV firmware, it provides exceptional stability, accurate telemetry, and versatile connectivity for both small and mid-size UAVs.
1.2. Product Features
- MCU: STM32F405RGT6, ARM Cortex-M4, 168 MHz clock speed.
- IMU: ICM42688-P high-precision 6-axis gyroscope/accelerometer.
- Barometer: SPL06-001 digital air pressure sensor.
- Built-in PDB: Integrated power distribution with current sensing up to 90 A continuous / 132 A burst.
- Input Voltage: 6 V – 30 V (2S – 6S LiPo).
- BEC Outputs: 5 V @ 1.5 A for FC; Vx 5 A configurable to 5 V or 6 V for servos.
- UART Ports: 5 UARTs + soft-serial option for peripherals.
- I²C Bus: 1 × I²C for external sensors or compass modules.
- PWM Outputs: 12 channels for motor and servo control.
- OSD: AT7456E analog video OSD chip.
- Dual Camera Inputs: C1/C2 switchable video channels for FPV or dual-camera configurations.
- Firmware Targets: ArduPilot (MatekF405-TE) / INAV (MATEKF405TE).
- Mounting Pattern: 22 × 22 mm (Φ2 mm holes).
- Dimensions: ≈ 31 × 26 × 16.5 mm; Weight: ≈ 10 g.
1.3. Applications
- Fixed-Wing Aircraft: Ideal for wings, VTOL, and mapping UAVs.
- FPV Planes: Dual camera support for analog and digital FPV systems.
- Long-Range Platforms: Reliable telemetry and power sensing for endurance builds.
- Research & Development: Supports ArduPilot/INAV for professional UAV experimentation.

- Supports ArduPilot target
MatekF405-TEand INAV targetMATEKF405TE. - Ensure current sensor calibration is properly configured for accurate telemetry (scale ~250).
- Dual-camera input (C1/C2) can switch between analog FPV feeds via firmware.
- Use 5 V / 6 V BEC depending on servo requirements — verify servo voltage before powering.
- Mount securely using 22 × 22 mm pattern with vibration damping to maintain IMU accuracy.
5. Environmental Conditions
