While the development of the Raspberry Pi system has always taken place in the United Kingdom, until now it was produced in China. For the revision of the Rapsberry Pi, the developers have moved production to the UK, and have signed up with Sony and Premier Farnell.
Initially, the Raspberry Pi Foundation stated that it would be impossible to sell model A for $25 and model B for $35 if the systems were produced in the United Kingdom, although it seems that has changed. A Welsh team of thirty has been employed to manufacture the 30,000 ordered Raspberry Pi systems. Sony is responsible for production and logistics of the chips and other components, while keeping the product's green image into account as well.
Feedback from the early Raspberry Pi adopters has led to some minor changes in the new Raspberry Pi Revision 2.0. This new revision still has a $25 recommended price but has an improved circuit for its USB hub, which should improve its reliability. The GPIO connector has been revised and mounting holes are now present on the board.
To identify your ordered version, “cat/proc/cpuinfo” can be entered into the terminal, after which a number is displayed. If this number is either a 4, 5 or 6, then you're dealing with revision 2.0. Revision 1.0 will display either a code 2 or 3.
Revisie 2.0 is identified by its mounting holes and the printing 'Made in the UK'
