Raspberry Pi is a series of inexpensive single board computers. At one time, it was suggested that we build a [[VTLUUG:Beowulf Cluster|Beowulf cluster]] out of [[Raspberry Pi cluster|Pis]].

Raspberry Pis do not have onboard storage (except for the Compute Module), and they do not have onboard WiFi or Bluetooth(excepting the B 3).All Pis (except for the Compute Module) support 3.5mm audio out (poor quality, but useable), HDMI out supporting 1080p30, and composite SD video out. Some also support I2S audio out.All Pis feature the VideoCore IV GPU, which is fairly powerful given the rest of the components. It's roughly as powerful as the GPU in the iPhone 4s.

The Pi can run various distros of Linux, as well as BSDs and some other Unixes ported to ARM. The official main distro is Raspbian, which is based off of Debian Jessie. The Pi also supports Arch LinuxARM, OpenELEC , and RISC OS.
