SP Racing F4 Evo Flight Controller

Designed by the cleanflight creators, the SP Racing F4 Evo uses next generation F4 hardware to take full advantage of all the latest cleanflight features.  This fifth generation SP racing flight controller is fifth generation of epic cleanflight flight controller boards, designed right here in the UK.  So if you are looking for the best cleanflight board, that is directly linked with cleanflight development then the F4 Evo is for you!

By purchasing an official cleanflight controller a protion of the sales go back to the development team to help improve the hardware and software, its the reason why cleanflight exists.

Sp Racing F4 Evo Features

• Highly Practical – highly flexible installation options and you can choose from pin headers, or direct solder wires
• Durable – all the main I/O connectors use through hole connectors for crash proof resilience
• Stackable – Can mount onto compatible PDB’s or OSD’s with just 2 through hole pins in each corner.
• Next Generation CPU and Sensors – Using the STM32405 CPU running at 168Mhz along with ICM20602 connected directly via SPI, to ensure processing of more sensor data faster than ever before.  Also the F4 Evo has full Dshot Support

At the end of the day, the three main features that make this board stand out from the rest is first teh fact that you are contributing back to the cleanflight development.  The SPI connection to the IMU which allows you to get sensor readings crazy fast, while the all new ICM IMU is more noise tolerant and accurate than any of the MPU series sensors.  Also the micro SD card allows you to record up to 32GB of black box data.  Compared to the dataflash chips which hold on about 128mb, you can record as much data as you want, and as quickly as you want without ever worrying about the storage.  Also not to mention this board was designed by the Cleanflight creator, Dominic Clifton, so you know it will work well!

Full Feataure List

• Next-generation STM32 F4 processor with hardware floating point unit for efficient flight calculations and faster ARM-Cortex M4 core. (STM32405 CPU, 168Mhz inc FPU)
• MicroSD-Card socket for black box flight log recorder - optimize your tuning and see the results of your setup without guesswork.
