The Raspberry Pi



The Raspberry Pi is a credit-card sized computer with Broadcom BCM2835 System on a Chip (SoC) which includes an ARM1176JZF-S (ARM11 family, ARMv6 architecture) processor at 700 MHz.
The Revision B Board has 512 MB of RAM shared with the GPU. More info about the Raspberry Pi can be found on the Raspberry Pi Official website and on Wikipedia.
As Operating System I use Raspbian (A Debian wheezy port, optimised for the Raspberry Pi).
A new version of Raspberry Pi, the Raspberry Pi 2 Model B, was released on 2 February 2015. It has a 900MHz quad-core ARM Cortex-A7 CPU (ARMv7-A architecture) and 1 GB of RAM.
