Features

The SPRacingF3 gives you all the features you need for the heart of your aircraft, whether you're into FPV racing, acrobatic flying or aerial photography it's perfect.
Supports a variety of aircraft, tricopters, quadcopters, hexacopters, octocopters, planes and more.

Flight Performance

The SPRacingF3 builds on tried and tested software, processor and sensor technology to make your aircraft fly like it's on rails.

No-Compromise I/O

Use all the features all the time; e.g. Connect your OSD + SmartPort + SBus + GPS + LED Strip + Battery Monitoring + Sonar + 8 motors - all at the same time!

Configurable

The SPRacingF3 runs Cleanflight which can be configured to suit your needs using a cross-platform GUI (Windows/OSX/Linux).

Tiny and lightweight

The SPRacingF3 has a standard 36x36mm form-factor with 30.5mm mounting holes and weighs just 6 grams.

Flight Logging

On-board high-capacity black box flight log recorder - optimize your tuning and see the results of your setup without guesswork.

Next-Generation CPU

The SPRacingF3 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.

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.

Broad RC receiver Support

Supports SBus, SumH, SumD, Spektrum1024/2048, XBus, PPM, PWM receivers. No external inverters required (built-in).

Programmable LEDs

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

Battery Monitoring

Battery monitoring ports for voltage and current.

Sonar

Sonar support for precision low-altitude hold.

I2C Port

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

Buzzer

Buzzer port for audible warnings and notifications.

SPRacing F3 Top and bottom

The SPRacingF3 Design is:

  • Practical - Easy to access connectors and solder pads.
  • Configurable - Choose to use connectors, solder pads or pins.

Cleanflight

The SPRacingF3 runs the open-source Cleanflight flight control (FC) software which has an ever-growing community of friendly developers and users. Being open-source means that you too can contribute to the system.

Cleanflight comes with a detailed manual that is reviewed and maintained by the Cleanflight developers and community. No more out-of-date wiki pages and second-hand information.
