The Raspberry Pi is a single-board computer developed in the UK by the Raspberry Pi Foundation.
The design is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 128 or 256 MB of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage.
Features
The foundation plans to release two models at launch. Model A will have 128 MB RAM memory, one USB port and no Ethernet controller, and will cost US$25, while model B will contain 256 MB RAM memory, two USB ports and a 10/100 Ethernet controller and will cost US$35.
Though the Model A doesn't have an RJ45 Ethernet port, it can connect to a network by using a user supplied USB Ethernet or Wi-Fi adapter. As typical of modern computers, generic USB keyboards and mice are compatible with the Raspberry Pi.
The Raspberry Pi will use Linux-based operating systems. Debian GNU/Linux, Iceweasel, Calligra Suite and Python are planned to be bundled with the Raspberry Pi.

- Notes
- The 26-pin GPIO connector is not assembled on the board. The end-user must purchase and solder a 13x2 pin header with 0.1-inch (2.54mm) spacing. The pin header can be either a straight pin header, mounted on either the bottom or the top, (to connect to a "daughterboard") or it can be a right-angle shrouded box connector for use with a ribbon cable.
