Description

The SpeedyBee F405 Mini Flight Controller is engineered for pilots demanding a high-performance, feature-rich brain for their FPV drones. Its core is the STM32F405 microcontroller, which provides ample processing headroom for advanced Betaflight features, while the ICM42688P IMU ensures precise, low-noise attitude estimation critical for stable flight and acrobatic maneuvers.

Beyond its core processing, the board integrates a suite of modern conveniences. The built-in Bluetooth module eliminates the need for a separate adapter, allowing for real-time PID tuning and configuration changes directly from a mobile device. The integrated AT7456E OSD chip delivers crisp, customizable on-screen display data, and the built-in barometer supports altitude hold functions. Its compact 20x20mm form factor makes it an ideal choice for tight builds, from 3-inch toothpicks to 5-inch racing quads.

Key Features

  • High-Performance Processing: STM32F405 MCU with ample flash and RAM for complex flight control firmware.
  • Advanced IMU: ICM42688P gyro/accelerometer combo offers high-resolution, low-latency sensor data.
  • Wireless Convenience: Integrated Bluetooth for cable-free Betaflight configuration and real-time tuning.
  • Robust Connectivity: Type-C USB port and dedicated UARTs for peripherals like DJI Air Units, VTXs, and GPS.
  • Integrated OSD: AT7456E chip provides a stable, customizable on-screen display overlay.
  • Compact Design: 20x20mm mounting footprint optimizes space in minimalist and performance-focused drone frames.
  • Built-in Barometer: Enables altitude hold and variometer functions for more stable flight modes.

Applications

  • High-performance 3-inch to 5-inch FPV racing and freestyle drone builds.
  • Compact micro and mini long-range FPV drones requiring advanced telemetry and OSD.
  • Betaflight-based drones where wireless tuning via Bluetooth is a priority.
  • Builds integrating DJI Digital FPV System (V1/V2) or HDZero VTX for video feed overlay.
