Flight Controller F405-MINITE
1. Product Summary
1.1. Product Description
The Matek Systems F405-MINI TE is a high-performance mini flight controller designed for compact FPV and UAV builds. Featuring the STM32F405RGT6 MCU, advanced ICM42605 / ICM42688-P IMU, and SPL06-001 barometer, it delivers excellent flight stability and sensor precision. The controller supports both 20×20 mm and 30.5×30.5 mm mounting patterns and includes dual BEC outputs for 5 V and 10 V power rails — ideal for powering video systems or DJI Air Units.
1.2. Product Features

4. Integration & Usage Notes
- Supports firmware targets
MATEKF405-TEandMATEKF405MINIfor INAV / ArduPilot / Betaflight. - No built-in current sensor — use external PDB or inline sensor for current monitoring.
- 10 V BEC recommended for video systems or DJI Air Unit when VBAT > 11 V.
- IMU model varies by batch; ensure firmware supports ICM42688-P if newer version.
- Mount with soft vibration dampers for best sensor stability.
5. Environmental Conditions

| Operating Temperature | -20 °C ~ +80 °C |
| Storage Temperature | -40 °C ~ +90 °C |
| Humidity | 5 % ~ 95 % (non-condensing) |
6. Precautions
- Do not exceed 30 V input voltage on VBAT input.
- Use correct polarity and verify ground connections before powering on.
- When using 10 V output for video transmission, ensure adequate cooling.
- Keep IMU area free of direct heat sources for accurate sensor performance.
- For external current sensing, use high-quality PDB with calibration support.
