Raspberry Pi is a project being developed by the Raspberry Pi Foundation that wants to produce a very cheap computer that is as small as a credit card. The main purpose of the project is to provide cheap hardware and software solutions for teaching programming languages to kids, but it had lots of attention from IT enthusiasts because of the price and the endless possibilities of usage.
When I first saw this project, my first thought was :
“I wonder if this thing can be used to make an HTPC with a DVB-S2 USB tuner. From the hardware point of view it certainly can. I can´t wait to get my hands on one of this delicious Raspberries.”
Here is the specification of Raspberry Pi from the eLinux Wiki.
The first product is the size of a credit card, and is designed to plug into a TV or HDMI monitor. It comes in two variants, model A and B, with B having more features. The expected price is $25 for model A and $35 for model B. The GPIO pins on each board allow the use of optional expansion boards.
|Model A||Model B|

|Memory (SDRAM)iB||256 MiB (previously listed as 128MiB for model A, but an upgrade to 256MiB was announced on 29 Feb 2012)|
|USB 2.0 ports:||1(provided by the BCM2835)||2 (via integrated USB hub)|
|Video outputs:||Composite video|Composite RCA, HDMI (not at the same time)|
|Audio outputs:||TRS connector|3.5 mm jack, HDMI|
|Audio inputs:||none, but a USB mic or sound-card could be added|
|Onboard Storage:||Secure Digital|SD / MMC / SDIO card slot|
|Onboard Network:||None||10/100 wired Ethernet RJ45|
|Low-level peripherals:||General Purpose Input/Output (GPIO) pins, Serial Peripheral Interface Bus (SPI), I²C, I²S, Universal asynchronous receiver/transmitter (UART)|
|Power ratings (provisional, from alpha board):||500mA, (2.5 Watt)||700mA, (3.5 Watt)|
|Power source:||5V via Micro USB or GPIO header|
|Size:||85.60mm x 53.98mm (3.370 × 2.125 inch)|
