# Board - Seriously Pro SP Racing F3 (Acro/Deluxe)
|
||
|
|
|
||
|
|
The Seriously Pro Racing F3 board (SPRacingF3) is the first board designed specifically for Cleanflight.
|
||
|
|
|
||
|
|
Purchasing boards directly from SeriouslyPro / SP Racing and official retailers helps fund Cleanflight development, it's the reason the Seriously Pro boards exist! Official retailers are always listed on the SeriouslyPro.com website.

## Hardware Features
|
||
|
|
|
||
|
|
* 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!
|
||
|
|
* On-board high-capacity black box flight log recorder - optimize your tuning and see the results of your setup without guesswork. (Acro and Deluxe)
|
||
|
|
* Next-generation STM32 F3 processor with hardware floating point unit for efficient flight calculations and faster ARM-Cortex M4 core.
|
||
|
|
* Stackable design - perfect for integrating with OSDs and power distribution boards.
|
||
|
|
* 16 PWM I/O lines for ESCs, Servos and legacy receivers. 8 available on standard pin headers. 8 via side mounted connectors.
|
||
|
|
* Supports SBus, SumH, SumD, Spektrum1024/2048, XBus, PPM, PWM receivers. No external inverters required (built-in).
|
||
|
|
* Dedicated output for programmable LEDs - great for orientation, racing and night flying.
|
||
|
|
* Dedicated I2C port for connection of OLED display without needing flight battery.
|
||
|
|
* Battery monitoring ports for voltage and current.
|
||
|
|
* Buzzer port for audible warnings and notifications.
|
||
|
|
* Solder pads in addition to connectors for Sonar, PPM, RSSI, Current, GPIO, LED Strip, 3.3v,
|
||
|
|
* Developer friendly debugging port (SWD) and boot mode selection, unbrickable bootloader.
|
||
|
|
* Symmetrical design for a super tidy wiring.
|
||
|
|
* Wire up using using pin headers, JST-SH sockets or solder pads. Use either right-angled or straight pin-headers.
|
||
|
|
* Barometer mounted on the bottom of the board for easy wind isolation.

|
* You cannot use SWD and USART2 at the same time.
|
||
|
|
* You may encounter flashing problems if you have something connected to the USART1 RX/TX pins. Power other devices off and/or disconnect them.
