About
The Seriously Pro Racing F4 EVO Flight Controller (SPRacingF4EVO) was designed to give awesome flight per-
formance in a stackable race-ready package. It has a high-performance CPU, the latest sensors, race timing &
logging technology backed by excellent connectivity options at a wallet-friendly price.
Featuring a race timing transponder system the SPRacingF4EVO is truly designed for racers. Analyze your race
and flight telemetry/blackbox logs using the built-in MicroSD card socket.
The SPRacingF4EVO 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.

Software
The SPRacingF4EVO 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 No more out-of-date wiki pages and second-hand information.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 STM32F3-based boards and to set the benchmark for a wallet-friendly STM32F4 based board with 8 DSHOT
outputs and simultaneous Transponder, LED Strip and Telemetry support.
The F4EVO uses a similar layout to the SP Racing F3 EVO boards; the stack-pins, ESC/Servo outputs and connec-
tors are in the same location on the F4 EVO as they are on the F3 EVO, F3 Acro and Deluxe boards for maximum
SPRacingF4EVO
