About
The Seriously Pro Racing F3 EVO Flight Controller (SPRacingF3EVO) was designed to give awesome flight perfor-
mance in a stackable race-ready package. It has the latest sensors, race timing & logging technology backed by
excellent connectivity options at a wallet-friendly price.
Featuring a race timing transponder system the SPRacingF3EVO is truly designed for racers. Analyze your race
and flight telemetry/blackbox logs using the built-in MicroSD card socket.
The SPRacingF3EVO 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.
Features
•
Next-generation STM32 F3 processor with hardware floating point unit for efficient flight calculations and faster ARM-Cortex M4 core.
•
MicroSD-Card socket for black box flight log recorder - optimize your tuning and see the results of your setup without guesswork.
•
Race transponder built in - just turn up at a race and have your lap times recorded.
•
Features the latest Accelerometer, Gyro and Mag/Compass and Baro/Altitude sensor technology.
•
Wire up using using pin headers for all major connections for excellent crash-durability. Use either right-angled or straight pin-headers.
•
No compromise I/O. Use all the features all the time; e.g. Connect your USB + OSD + Sma SBus + LED Strip + Battery Moni 8
motors - all at the same time!
•
8 PWM output lines for ESCs and Servos. Arranged for easy wiring on standard pin headers.
•
Supports direct connection of SBus, SumH, SumD, Spektrum1024/2048, XBus receivers. No external inverters required (built-in).
•
Supports direct connection of 3.3v Spektrum Satellite receivers via 3 pin through-hole JST-ZH connector.
•
Dedicated PPM receiver input.
•
3 Serial Ports - NOT shared with the USB socket.
•
Telemetry port
•
Micro USB socket.
•
Dedicated output for programmable LEDs - great for orientation, racing and night flying. (Currently mutually exclusive with the Transponder).

Battery monitoring for voltage and current.
•
RSSI monitoring (analogue or PWM).
•
Buzzer port for audible warnings and notifications.
•
Developer friendly debugging port (SWD) and boot mode selection, unbrickable bootloader.

Software
The SPRacingF3EVO runs the open-source Cleanflight flight control (FC) software which has an ever-growing com-
munity 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.
See http://cleanflight.com for links to the manual. PDF copies can be downloaded from the github releases pag-
es. Ensure you reference the manual that is appropriate to your firmware version.
History
The hardware was designed by the lead developer of Cleanflight to be more capable than the previous-genera-
tion STM32F1-based boards and to set the benchmark for a wallet-friendly STM32F3 based board.
The EVO uses a similar layout to the SP Racing F3 Acro & Deluxe boards; the stack-pins, ESC/Servo outputs and
connectors are in the same location on the F3 EVO as they are on the Acro and Deluxe boards for maximum
mounting compatibility with existing products.
Compared to the F3 Acro/Deluxe the EVO uses newer sensor technologies, adds MicroSD and Transponder func-
tionality and drops PWM receiver (1 wire per channel) support.
