So one downside to the Cubieboard is that the pin spacing on the U14/U15 headers is 2mm, rather than the more common 2.54mm (0.1") headers that you find on protoboards and breadboards. After searching a bit for an easy prototyping solution, I finally settled on a pair of 50 pin IDC cables off of ebay. They're not too expensive, and you have all the wires you need in a single connector.
