Really cheap-only about 17 euros, is supported by free software and is fully equipped

Numerous projects initiated by governments and organizations have sought to place the student service computer equipment to improve their school performance and better prepare them for the future. A foundation of the United Kingdom believes it has found the key: a tiny computer and really cheap, supported by free software.

David Briggs, head of the video game company that created Frontier Development Kinectimals for Kinect titles like "Xbox 360 and Wii LostWinds, and Pi Raspberry Foundation has presented its small building that it hopes to reach schools throughout the world thanks to its usability and price.

The minicomputer also called Raspberry Pi, is the size of a pen drive or a finger and will be fully equipped for sale for about $ 25 (about 17 euros). How equipped? Therefore, fully prepared to sail, used office tools and the like or play the high definition content. Consist of a 700MHz ARM11 core supported by a SRAM memory of 128MB on OpenGL ES 2.0, ie enough to reproduce composite video to 1080p via HDMI output from one end.

In the other, a USB port to connect to a control hub. And by the chip, a slot for SD memory connection, MMC or SDIO. All according to the provisional version.

It's even cheaper than the project launched by Indra who managed to make chips in India for about $ 35.

Free software Hardware efficient search
For this project Raspberry Pi Foundation will finally turn into something really useful, it must increase the amount of specialized software for education available for their platform.

The social purpose of this organization is, quoted verbatim his website, "promote the study of computer science and related issues, especially at school, and put the fun back to the study of computing." Openly ask why developers collaboration program to fit your project.

This initiative is four times cheaper than Lapton One per Children (OLPC), which has minimum quality laptops to children in 7 countries in the Americas, Africa and Asia. The advantage of OLPC is that it is a complete product, including all hardware peripherals. However, the project Raspberry Pi is much more versatile and getting the price right hardware can be optimized, such as screens and keyboards donated by the other party of society with sufficient resources to continue the very high renewal rate and the technological gap.
