-The Strawberry Cake is a small, cheap embedded ARM board. Unlike the Raspberry Pi, Strawberry Cake really exists. It is a board design that challenges you to assemble it yourself, to practice your fine-pitch SMD soldering techniques. It can be assembled with a normal soldering station, or - better - reflow soldered. Ongoing miniaturisation is a FACT, if you want to do electronics without being stuck in the 80's, you need SMD!

 It will not run Linux since there is not enough memory, but it will spin circles around arduino's.
