Raspberry 1 circuit board diagram

One great thing about technology is all the great disruptive innovation it makes possible. And while some gadgets cost a large amount of money it is also great how many really cheap but nevertheless extremely cool gadgets we get to choose from. The folks at Rasberry Pi are creating this computer (alpha boards have been sent to the manufacturer), that just a bit larger than a credit card, and is designed to plug into a TV or be combined with a touch screen for a low cost tablet. The expected price is $25 for a fully-configured system.

The ICs used in the design are an ARM-based application processor (center) and an SMSC LAN9512 USB 2.0 hub and 10/100 Ethernet controller (right and down from center). The SDRAM is mounted on top of the application processor in a PoP configuration.

Following the example of the BBC Micro, we intend to launch both a Model A device (lacking the LAN9512, and with 128MB of RAM) at the $25 price point, and a Model B device (including the LAN9512, and with 256MB of RAM) for a $5-10 additional cost. We remain confident of shipping before the end of 2011.

The Raspberry Pi Foundation is a UK registered charity which exists to promote the study of computer science and related topics, especially at school level, and to put the fun back into learning computing.

They are developing, manufacturing and distributing an ultra-low-cost computer, for use in teaching computer programming to children and expect the computer to have many other applications both in the developed and the developing world.
