SPIDER Automation Flip32 OMNIBUS F4 Flight Controller | STM32F405, MPU6000 SPI IMU & Integrated OSD for FPV Racing Drones
Description
The Flip32 OMNIBUS F4 Flight Controller is an integrated flight-control and OSD board designed for FPV racing multirotors and compatible UAV platforms. Based on the STM32F405 32-bit microcontroller, it combines inertial sensing, video telemetry display, receiver interfaces, PWM outputs and onboard voltage regulation in a compact PCB layout. Its integrated architecture reduces the need for separate flight-control and OSD modules in compatible FPV builds.
The board uses an MPU6000 six-axis inertial sensor connected through SPI, incorporating a 3-axis gyroscope and 3-axis accelerometer for motion measurement. Its integrated OSD uses an AB7456/MAX7456-compatible display architecture, allowing supported flight information to be overlaid onto the FPV video feed. OSD settings can be managed through compatible Betaflight firmware and configuration tools.
For aircraft connectivity, the Flip32 OMNIBUS F4 provides six PWM outputs and supports SBUS, PPM, DSM, DSM2 and DSMX receiver connections through the designated interfaces. It also incorporates a 5V, 1.5A onboard regulator, buzzer and LED-strip ports, and 128Mbit flash memory. Its 36 × 36mm board size and 30.5 × 30.5mm mounting-hole pattern support installation in compatible multirotor frames.

Flight-Control Processing & Inertial Measurement
The STM32F405 microcontroller serves as the primary processing unit of the Flip32 OMNIBUS F4. It executes the installed flight-control firmware and processes receiver commands, inertial sensor measurements and configured output signals.
The onboard MPU6000 inertial measurement unit combines a 3-axis gyroscope and 3-axis accelerometer. The gyroscope measures angular velocity, while the accelerometer measures linear acceleration. These measurements provide the flight-control firmware with motion data used for aircraft attitude estimation and stabilization.
The MPU6000 communicates with the processor through the SPI interface. This digital sensor connection forms part of the board’s integrated flight-control architecture and supports the sensor-processing requirements of compatible firmware.
Integrated OSD & FPV Video Telemetry
The Flip32 OMNIBUS F4 incorporates an AB7456/MAX7456-compatible OSD chip connected to the main flight-control processor. This integration allows supported flight information to be overlaid onto the FPV video feed without requiring a separate external OSD module.
With compatible Betaflight firmware and configuration software, available OSD elements can be configured through the flight-controller setup interface. The integrated design simplifies telemetry configuration by combining the flight-control and OSD functions on the same board.
Receiver Connectivity & PWM Outputs
The flight controller supports multiple receiver connection formats for integration with compatible RC radio systems. SBUS and PPM receiver inputs are provided through pin headers, while DSM-family receiver connections use the designated plug interface.
- SBUS: Supported through the designated receiver pin-header connection.
- PPM: Supported through the designated receiver pin-header connection and compatible firmware configuration.
- DSM: Supported through the specified receiver plug.
- DSM2: Supported through the specified receiver plug.
- DSMX: Supported through the specified receiver plug.
- PWM Outputs: Six output channels are provided through pin-header connections for compatible ESC and servo-control equipment.
Receiver protocol selection, signal assignment and output configuration must match the connected receiver, installed firmware and board connection layout. Confirm the pinout before wiring.
Onboard Voltage Regulation & Power Management
The Flip32 OMNIBUS F4 incorporates an onboard 5V voltage regulator rated at 1.5A. The product design describes direct LiPo battery input through the board’s designated power connection, with the onboard regulator providing the lower-voltage supply required by the flight controller and compatible equipment.
The regulator’s 1.5A rating represents its specified output-current capacity. The actual available current for external peripherals depends on the total load, thermal conditions and board power design. Verify the designated battery-input connection and supported battery-cell range against the exact hardware revision before applying flight-battery voltage.
Buzzer, LED Strip & ESC Protocol Support
Dedicated buzzer and LED-strip ports provide additional integration options for compatible flight-status indicators and lighting accessories. The buzzer connection can be used with a compatible audible indicator, while the LED-strip port supports an appropriate addressable LED accessory when enabled by the firmware.
The board also supports DShot ESC control when configured with a compatible Betaflight firmware target. The supplied product information identifies the AirbotF4 target for the specified Betaflight 3.1 DShot configuration. Verify firmware-target compatibility and output assignments before connecting ESCs.
