F405-OSD – Beta flight

Home » F405-OSD – Beta flight

The “F405-OSD” is a flight controller designed specifically for multirotor drones, particularly those used in FPV (First Person View) racing, freestyle, and aerial photography. Let’s break down its key features and characteristics:

1. Brand and Model:

  • F405-OSD: This indicates both the brand and model name of the flight controller. It is likely manufactured by a company specializing in drone electronics and accessories.

2. Integrated OSD (On-Screen Display):

  • OSD Functionality: The flight controller includes an integrated OSD, allowing real-time display of critical flight data directly on the FPV video feed. This data typically includes battery voltage, flight time, RSSI (Received Signal Strength Indicator), and other telemetry information.
  • Customizable OSD Layout: Users can customize the OSD layout and contents using Betaflight or other compatible firmware configurators, tailoring the display to their preferences and requirements.

3. Processor:

  • F405 Processor: Indicates the type of microcontroller or processor used in the flight controller. The “F405” likely refers to a 32-bit ARM Cortex-based processor, providing ample computing power for flight control and OSD functionality.
  • High Performance: The F405 processor offers high performance, allowing for fast and responsive flight control algorithms and OSD updates.

4. Betaflight Compatibility:

  • Betaflight Firmware: The flight controller is compatible with Betaflight firmware, one of the most popular open-source firmware options for FPV drones. Betaflight offers a wide range of features, configurability, and community support.
  • Betaflight OSD Integration: The flight controller seamlessly integrates with Betaflight OSD features, allowing users to access and configure OSD settings directly from the Betaflight configurator software.

5. Additional Features:

  • Integrated PDB (Power Distribution Board): Some flight controllers include an integrated PDB, simplifying wiring and reducing the overall weight and size of the drone’s electronic stack.
  • Voltage Regulation: Built-in voltage regulators ensure stable power delivery to all connected components, preventing voltage spikes or drops that could affect performance.

6. Compatibility:

  • Frame and Component Compatibility: Ensure compatibility with your drone’s frame and other electronic components such as ESCs, motors, and receivers.
  • Firmware Updates: Regular firmware updates may be available to add new features, improve performance, or address any issues discovered after the initial release.


The F405-OSD flight controller with Betaflight compatibility offers a robust platform for building high-performance FPV drones. With integrated OSD functionality, customizable OSD layouts, a powerful F405 processor, and Betaflight firmware support, it provides pilots with advanced features and flexibility for their FPV flying needs. When combined with compatible components and configured appropriately, it can deliver smooth, responsive flight performance and an immersive FPV experience.
