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 LED
Dedicated output for programmable LEDs - great for orientation, racing 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.
