The Raspberry Pi 2 is an inexpensive ($35) and self-contained micro-computer that features a 900 MHz, 32-bit quad-core ARM processor and 1 GB of RAM. Built by the Raspberry Pi Foundation, it is designed to be an easy and accessible platform to promote computer science. The Pi has also become a popular computer for hobbyists, who use it for personal projects, video game emulators and digital media playback.
context_page_description: The Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to put the power of computing and digital making into the hands of people all over the world. If at the beginning the aims of the Raspberry Pi project were leaned towards the promotion of teaching of basic computer science in schools and in developing countries, it rapidly expanded into a wider range of uses, as the original model became far more popular than anticipated, selling outside its target market for uses such as robotics. It is now widely used even in research projects, such as for weather monitoring because of its low cost and portability. It does not include peripherals or cases. However, some accessories have been included in several official and unofficial bundles.
  After the release of the second board type, the Raspberry Pi Foundation set up a new entity, named Raspberry Pi Trading, and installed Eben Upton as CEO, with the responsibility of developing technology. The Foundation was rededicated as an educational charity for promoting the teaching of basic computer science in schools and developing countries.
context_section_description: Although often pre-configured to operate as a headless computer, the Raspberry Pi may also optionally be operated with any generic USB computer keyboard and mouse. It may also be used with USB storage, USB to MIDI converters, and virtually any other device/component with USB capabilities, depending on the installed device drivers in the underlying operating system (many of which are included by default).
  Other peripherals can be attached through the various pins and connectors on the surface of the Raspberry Pi.
caption: The Model 2B boards incorporate four USB ports for connecting peripherals.
