# Board - Seriously Pro SP Racing F3 EVO
The Seriously Pro Racing F3 Evo board (SPRacingF3EVO) is the evolution of 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.
Full details available on the website, here:
http://seriouslypro.com/spracingf3evo
## Hardware 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 + SmartPort + SBus + GPS + LED Strip + Battery Monitoring + 8 motors - all at the same time! (Sonar will be supported in CF 1.14)
* 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).
* Dedicated I2C port for connection of OLED display without needing flight battery.
* 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.
* Symmetrical design for a super tidy wiring.
* JST-SH sockets only for I2C, UART2 and SWD. UART2 also on through-hole pins.
* Flashing via USB or serial port.
* Stackable design - perfect for integrating with OSDs and power distribution boards.
* Standard mounting - 36x36mm with standard 30.5mm mounting holes.
* LEDs for 3v, 5v and Status for easy diagnostics.
* Copper-etched Cleanflight logo.
## Serial Ports
