PDF icon Manual1.29 MB

The Seriously Pro Racing F3 Mini (SPRacingF3Mini) is the second flight controller designed specifically for Cleanflight by none other than its lead developer Dominic Clifton - Aka Hydra. This next generation F3 board 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 compatible with micro quads and FPV racing drones. It really is the Rolls Royce of flight control boards and the only FC that supports all the latest Cleanflight features.

The SP Racing F3 Mini includes a full set of sensors including: accelerometer, gyro, compass & barometer sensors. It also has probably the greatest RC compatibility of any FC on the market. It supports; Sbus, SumH, SumD, Spektrum1024/2048, XBus, PPM without an inverter needed, these are built in. It also the first flight controller to include a built in race timing transponder system for recording your lap times and a microSD card slot, which allows you to log your flight data for post race analysis and tuning. As flight controllers go, you don't get much more race ready than this one.

Purchasing boards directly from SeriouslyPro / SP Racing and official retailers helps fund Cleanflight software development, it's the reason the Seriously Pro boards exist!

This new Mk II version of the board includes a new high reliability voltage regulator with 2-6S support.


The SPRacingF3Mini has some awesome world-first features that makes it the FC 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.

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.

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!

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


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


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

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.


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

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.

Unique code

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

Programmable LEDs

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

Developer Friendly

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

OneShot ESC

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

Battery Monitoring

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


Sonar support for precision low-altitude hold.

I2C Port

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


Buzzer port for audible warnings and notifications.

Cleanflight Logos

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

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.
