Description

The SP Racing F3 ACRO Flight Controller is engineered for pilots demanding uncompromised performance in a compact, open-source platform. Its STM32F3 processor delivers faster loop times compared to previous-generation F1 boards, enabling sharper control response and more efficient flight calculations. The board’s symmetrical layout and extensive through-hole and JST-SH connector options provide exceptional flexibility for custom builds.

Designed with a no-compromise I/O philosophy, the controller allows simultaneous use of features like OSD, SmartPort telemetry, GPS, LED strips, battery monitoring, and up to 8 motor outputs. The dedicated ports for a buzzer, programmable LEDs, and always-powered I2C bus facilitate advanced functionality for racing orientation, low-altitude sonar hold, and external sensor integration, all within a robust and community-supported Cleanflight ecosystem.

Key Features

  • Next-generation STM32F3 72MHz ARM Cortex-M4 CPU with integrated hardware floating-point unit (FPU).
  • High-precision MPU6000 6-axis gyroscope and accelerometer sensor for stable flight dynamics.
  • Extensive connectivity with 8 dedicated PWM outputs, 3 hardware serial ports, and an always-powered I2C port.
  • On-board 16MB flash memory for high-capacity black box flight data logging and tuning analysis.
  • Built-in signal inverter for direct support of SBus, SumD, Spektrum, and other serial RC protocols.
  • Dedicated outputs for programmable LED strips, buzzer alerts, and battery voltage/current monitoring.
  • Compact, professional-grade PCB design with a symmetrical layout and configurable connection options.
  • Runs the open-source Cleanflight firmware with an active community for ongoing development and support.

Applications

  • 5-inch and 6-inch FPV racing quadcopters requiring high-performance acrobatic control.
  • Freestyle multirotor builds where low latency and extensive black box logging are critical for tuning.
  • Custom experimental drones leveraging the open-source Cleanflight platform and extensive I/O for add-ons like GPS, telemetry, and LED systems.
  • Lightweight micro and mini quadcopter builds where the compact 36x36mm form factor and 6g weight are advantageous.

Frequently Asked Questions

What is the difference between the SP Racing F3 ACRO and Deluxe versions?

The ACRO version is the standard model equipped with the core MPU6000 gyro/accelerometer, optimized for racing and acrobatic flight. The Deluxe version includes additional sensors, typically a barometer and magnetometer, providing altitude hold and compass heading functionality for more autonomous flight modes.

What firmware does the SP Racing F3 run, and is it configurable?

This board runs the open-source Cleanflight firmware. It is fully configurable via the Cleanflight Configurator, a cross-platform GUI tool for Windows, macOS, and Linux, allowing you to tune PIDs, set up flight modes, and configure all connected peripherals.

What RC protocols are supported natively by this flight controller?

The SP Racing F3 has a built-in signal inverter, providing direct support for serial protocols like FrSky SBus, Futaba S.Bus, SumH, SumD, Spektrum 1024/2048, and XBus. It also supports traditional PPM and PWM receiver inputs, offering broad compatibility without requiring additional hardware.

Can I use OneShot ESCs with this flight controller?

Yes, the SP Racing F3 has full support for OneShot and OneShot125 ESC protocols. This enables faster communication between the flight controller and ESCs, resulting in reduced latency, easier PID tuning, and a sharper, more responsive flight performance for acrobatic maneuvers.

What is the input voltage requirement, and how do I power the board?

The flight controller logic requires a clean 5V DC input. This is typically supplied via a 5V BEC from your Electronic Speed Controller (ESC) or a separate voltage regulator. The board features dedicated pads and ports for connecting this power, as well as for monitoring main battery voltage.
