# 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.

|
## 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.

|
|
| Value | Identifier | RX | TX | 5v Tolerant | Notes |
|
||
|
|
| ----- | ------------ | ------------ | ------------ | ----------- | ------------------------------------------------------------------------------------------- |
|
||
|
|
| 1 | USART1 | PA10 | PA9 | YES | 2 through-hole pins. Use for connecting to OSD/GPS/BlueTooth. |
|
||
|
|
| 2 | USART2 | PA15 | PA14 / SWCLK | YES | JST socket and PPM header. Use to connect to RX. |
|
||
|
|
| 3 | USART3 | PB11 / AF7 | PB10 / AF7 | NO | Available on 4 through-hole pins. 3.3V signals only ! Use for GPS, Spektrum Satellite RX, SmartPort Telemetry, HoTT telemetry, etc. |
|
||
|
|
|
||
|
|
* You cannot use SWD and USART2 at the same time.
|
||
|
|
* When using a Serial RX receiver the TXD (T2) pin cannot be used for telemetry. Use UART3 TXD instead.
|
||
|
|
* Software serial is not supported
|
||
|
|
* Windows DFU Flashing requires Zadig (see configurator)
