Raspberry Pi is a credit-card-sized (3.37-inch by 2.125-inch) single-board Linux computer based on an ARM processor. Developed by the Raspberry Pi Foundation in England, the Raspberry Pi Model B sells for just $35. A less expensive $25 version called the Model A is expected shortly.

Raspberry Pi is cheaper than competing products such as the $89 BeagleBone. The price difference is probably not significant for space applications at the present time, but we’re looking forward to see the day when a $64 price difference becomes significant.

Supply appears to be constrained at the present time. The Raspberry Pi Foundation is currently trying to limit sales to one per customer in order to spread them around. In the US, Raspberry Pi is available through Element 14.
