SP Racing F3 Mini Flight Controller


 Sold out 



The Seriously Pro Racing F3 Mini Flight Controller (SPRacingF3Mini) was designed to give awesome flight performance in a tiny race-ready package. It has the latest sensors, race timing and logging technology in a flexible form factor and also features a built-in voltage regulator (BEC). Includes built in Accelerometer, Gyro, Compass & Barometer Sensors; Transponder LEDs and Code; MicroSD card socket and pin headers.


The SPRacingF3Mini has some awesome world-first flight-controller features that makes it the board of choice for any new multi-rotor or fixed-wing build!

Jaw-Dropping Flight Performance

  • The SPRacingF3Mini uses advanced processor, sensor and software technologies to make your aircraft fly like it's on rails. The SPRacingF3Mini flight-controller and the Cleanflight software enables the precision flying you need for fast FPV racing.

Built-in 5v regulator (BEC)

  • The built-in 5V regulator makes wiring-up simpler and cheaper. Fixed-wing aircraft also become so easy: connect receiver, battery, 2 servos and an ESC and you're done!


  • The SPRacingF3Mini is the first and only mini board that features a MicroSD card socket for logging. Supports MicroSD/SDHC up to 32GB!


  • The SPRacingF3Mini runs Cleanflight which can be configured to suit your needs using a cross-platform GUI (Windows/OSX/Linux).


  • The only mini board to feature two built-in buttons. Uses currently include receiver binding, configuration reset and bootloader entry, more uses planned!

Unique code

  • Each SPRacingF3Mini comes with a unique QR-CODE so you can download your personal transponder code.

Developer Friendly

  • Developer friendly debugging port (SWD) and boot mode selection, unbrickable bootloader.

Battery Monitoring

  • Built in battery voltage monitoring, input for additional current monitoring.

I2C Port

  • I2C port always powered, perfect for external sensors or always-on OLED Screen.

Cleanflight Logos

  • The SPRacingF3Mini features a copper-etched Cleanflight logo so you can show your support!

Race Timing Transponder

  • The SPRacingF3Mini is the first and only mini board that features a race transponder system for recording your lap times. Each board comes with a special transponder code to identify you at race events. Compatible with i-LAP receiver systems. Two LEDs for clockwise and anti-clockwise race tracks.

Next-Generation CPU

  • The SPRacingF3Mini has an ARM Cortex-M4 72Mhz CPU with Math co-processor (FPU) for efficient flight calculations that gets more done in less time. Loop times up to ~2x as fast as previous-generation STM32F1 based boards.


  • The only full-featured mini-size board with USB socket which is not shared with serial ports. No more hassle configuring or flashing.

Tiny and extremely lightweight

  • The SPRacingF3Mini has a standard 36x36mm form-factor with 30.5mm mounting holes with detachable tabs for flexible mounting.The mini center section of the board measures 36x24mm.

Broad RC receiver Support

  • Supports SBus, SumH, SumD, Spektrum1024/2048, XBus, PPM. No external inverters required (built-in), receiver powered via flight battery or USB for easy configuration.

Programmable LEDs

  • Output for multi-colored LED strips - great for FPV racing, line-of-sight flying orientation and night flying.

OneShot ESC

  • Full support for OneShot ESCs for easy PID tuning and a sharper response.


  • Sonar support for precision low-altitude hold.


  • Buzzer port for audible warnings and notifications.

GPS Ready *

  • With a full-set of sensors (Accelerometer, Gryoscope, Compass and Barometer) each SPRacingF3Mini is capable of GPS Navigation * Available in Cleanflight soon, New GPS features under active development.



The hardware was designed by the lead developer of Cleanflight to be more capable than the previous-generation STM32F1-based boards and to set the benchmark for a fully-featured STM32F3-based mini board.
