The Seriously Pro Racing F3 Mini Flight Controller (SPRacingF3Mini) was designed to give awesome flight performance in a tiny race-ready package. It has the latest sensors, race timing and logging technology and a wealth of other features that makes it the board of choice for any new multi-rotor or fixed-wing aircraft build!

It has jaw-dropping fight performance using its advanced processer, sensor and software technologies to make your aircraft fly like it's on rails. Using Cleanflight software you get the precision flying responses you need for outstanding performance, especially fast FPV racing!

The SPRacingF3Mini is the first and only mini board that features a race transponder system for recording your lap times. Each board comes with a special transponder code to identify you at race events. Compatible with i-LAP receiver systems. Two LEDs for clockwise and anti-clockwise race tracks.

The SPRacingF3Mini has an ARM Cortex-M4 72Mhz CPU with Math co-processor (FPU) for efficient flight calculations that gets more done in less time. Loop times up to ~2x as fast as previous-generation STM32F1 based boards.  It also has a full-set of sensors (Accelerometer, Gryoscope, Compass and Barometer) making each SPRacingF3Mini capable of GPS Navigation as well as sonar support for precision low altitude hold.

 The SPRacingF3Mini is also the first and only mini board that features a MicroSD card socket for logging. Supports MicroSD/SDHC up to 32GB!  It is also the only full-featured mini-size board with USB socket which is not shared with serial ports.  No more hassle configuring or flashing and the SPRacingF3Mini runs Cleanflight, which can be configured to suit your needs using a cross-platform GUI (Windows/OSX/Linux). 

This is a truly amazing miniature flight controller that will set new standards in flight control systems for multirotors, quad racing and fixed wing aircraft.

Nowhere in the documentation does is say you must use a manual baud rate of 115,200 to flash the SPRacing cards to the latest Cleanflight. In FACT. the documentation shows a baud rate of 256,000 right on the online instructions. This WILL NOT work. You must select a Manual 115,200 baud rate to flash the SP Racing F303 controllers I was about to trash. Only by reading the newsgroups did I find this out. I assume this will also work with this SP Racing F3 Mini controller, like the one I trashed. I feel lucky that I found this out before I trashed them all, but a little resentful this very important detail was left out of the instructions. I would get 90% thru the flash and get a data read error when using 256,000 baud, but successful flash with 115,200baud.
