Components STM32F051

The Ellduino development board has the STM32F051 micro controller as its main and only processing unit. While we may change the choice for any later boards, we chose this MCU because it is relatively new, offers a good choice of peripherals, and has inexpensive packages if purchased in large numbers. Hence, it has the potential of allowing us to create low-cost PoE devices. (And, of course, Pekka Nikander happened to already know the chip quite well.)
