I thinkg SFE should sell the new Gertduino. It was created by the same guy who invented the Gertboard (duh!). It’s completely Arduino compatible and sits on top of the Raspberry Pi. It also has the same Arduino pinout so it should work with most sheilds. It has 6 built-in LEDs, an IR reciever, an RTC, two input buttons, and some other stuff.http://www.element14.com/community/serv … tduino.png
