A month before the start of sales of a mini-computer Raspberry Pi worth $ 25, the developers published the final scheme of the device. Now the development has come to the finish line, after a few days the first tests will begin, and if they pass without errors, the fee will be sent to the circulation. One of the fans from the Raspberry Pi forum printed this scheme on a 1: 1 scale to hold the physical model of the future computer in their hands. The size of the PCB is 85.6 x 53.98 mm, about as a credit card. It will be the smallest form factor on the market, about a third less pico-ITX.
