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 256 MB of RAM. The design does not include internal memory, instead relying on an SD card for booting and long-term storage.
XBMC for Raspberry Pi
Team-XBMC developers are working on porting XBMC to the Raspberry Pi using beta boards supplied by the RPi Foundation.

Notes
- ↑ 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.
- ↑ 2.0 2.1 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.
