Description

The OMNIBUS F4 Pro V3 Flight Controller is a community-driven evolution of the popular OMNIBUS F4 platform, engineered for clean, high-performance FPV quadcopter builds. Its core is the robust STM32 F403 microcontroller paired with an MPU6000 inertial measurement unit via SPI bus, ensuring low-latency, accurate flight data processing for acrobatic and racing applications.

Designed for direct battery power input, the board simplifies wiring with dedicated pin holes for all critical connections, including ESC signals, SmartAudio, and telemetry. The integrated 5V/3A BEC with LC filtering provides stable, clean power to peripherals like FPV cameras and video transmitters, reducing electrical noise in the video feed.

Key Features

  • High-Performance Processing: STM32 F403 MCU delivers the computational power needed for advanced Betaflight firmware features and filtering.
  • Comprehensive Sensor Suite: MPU6000 6-axis gyro/accelerometer on SPI bus ensures fast, reliable attitude data.
  • Built-In Power Monitoring: Integrated current and voltage sensor allows for real-time battery telemetry and consumption logging.
  • Extensive Connectivity: Features SBUS/PPM/DSMX receiver ports, SmartAudio V2 for VTX control, and dedicated pins for RSSI, buzzer, and IR lap transponders.
  • Dedicated Blackbox Logging: Onboard Micro SD card slot enables detailed flight data recording for tuning and analysis.
  • Clean Power Delivery: Includes a 5V/3A BEC with LC filter for camera and VTX to minimize video noise.
  • Modern Protocol Support: Fully supports D-Shot ESC protocols and is configurable via Betaflight Configurator OSD.
  • Optimized Footprint: 35x35mm board with 30.5mm mounting pattern fits a wide range of FPV frames.

Applications

  • 5-inch FPV racing and freestyle quadcopters requiring detailed Blackbox logging for tuning.
  • High-performance 3-inch to 7-inch multirotor builds needing integrated current sensing and clean power filtering.
  • Betaflight-based drones where direct battery connection and minimal wiring are priorities.
  • FPV builds utilizing SmartAudio-capable video transmitters for on-screen display control.
  • Drone racing applications where IR transponder pins can be used for lap timing systems.

Frequently Asked Questions

What firmware target should I use for the OMNIBUS F4 Pro V3 in Betaflight Configurator?

You must select the 'OMNIBUSF4SD' target within Betaflight Configurator. This firmware CubePilot is specifically compiled for this board variant and enables full functionality, including the SD card slot for Blackbox logging and the integrated current sensor.

Can I power this flight controller directly from my LiPo battery?

Yes, the board is designed for direct battery input. You connect your main LiPo battery leads (2S-6S) to the dedicated BAT and GND pins. The onboard 5V/3A BEC will then provide regulated, filtered power to the board itself and your connected peripherals like the receiver and FPV camera.

How do I connect and configure SmartAudio for my VTX?

SmartAudio V2 is managed via the J10 pin header on the board. You connect your VTX's SmartAudio wire to the designated TX pad on J10. Within Betaflight Configurator's Ports tab, you enable SmartAudio on the corresponding UART, and then you can control VTX channels and power settings directly from your OSD.
