Recently, I have been asked by Farnell if I were interested in taking part in their free product road test program.
As I like tinkering with electronics stuff, I said yes and chose the
STM32F4-Discovery board as an item to test.

The STM32F4-Discovery board is little development/evaluation board from ST to promote their STM32F4 micro controller series. The STM32F407 on the Discovery board consists of a 32 bit Corex-M4F ARM processor (which can run at up to 168 MHz), 192 kB of RAM (112+16+64 kB), 1 MB of flash memory and lots of peripherals (timers, DMA controllers, DACs, ADCs, two USB OTG ports, ...) and of course lots of general purpose I/O pins.
