The\u00c2\u00a0Raspberry Pi\u00c2\u00a0is a series of small\u00c2\u00a0single-board computers\u00c2\u00a0developed in the\u00c2\u00a0United Kingdom\u00c2\u00a0by the\u00c2\u00a0Raspberry Pi Foundation\u00c2\u00a0to promote the teaching of basic\u00c2\u00a0computer science\u00c2\u00a0in schools and in\u00c2\u00a0developing countries.\u00c2\u00a0The original model became far more popular than anticipated,\u00c2\u00a0selling outside its\u00c2\u00a0target market\u00c2\u00a0for uses such as\u00c2\u00a0robotics. It does not include peripherals (such as\u00c2\u00a0keyboards\u00c2\u00a0and\u00c2\u00a0mice) and\u00c2\u00a0cases. However, some accessories have been included in several official and unofficial bundles.<\/p>\n
The organisation behind the Raspberry Pi consists of two arms. The first two models were developed by the\u00c2\u00a0Raspberry Pi Foundation. After the Pi Model B was released, the Foundation set up Raspberry Pi Trading, with\u00c2\u00a0Eben Upton\u00c2\u00a0as CEO, to develop the third model, the B+. Raspberry Pi Trading is responsible for developing the technology while the Foundation is an educational charity to promote the teaching of basic computer science in schools and in developing countries.<\/p>\n
According to the Raspberry Pi Foundation, more than 5 million Raspberry Pis were sold by February 2015, making it the best-selling\u00c2\u00a0British computer.\u00c2\u00a0By November 2016 they had sold 11 million units,\u00c2\u00a0and 12.5m by March 2017, making it the third best-selling “general purpose computer”.\u00c2\u00a0In July 2017, sales reached nearly 15 million.\u00c2\u00a0In March 2018, sales reached 19 million.<\/p>\n
Several generations of Raspberry Pis have been released. All models feature a\u00c2\u00a0Broadcom\u00c2\u00a0system on a chip\u00c2\u00a0(SoC) with an integrated\u00c2\u00a0ARM-compatible\u00c2\u00a0central processing unit\u00c2\u00a0(CPU) and\u00c2\u00a0on-chip graphics processing unit\u00c2\u00a0(GPU).<\/p>\n
Processor speed ranges from 700\u00c2\u00a0MHz to 1.4\u00c2\u00a0GHz for the Pi\u00c2\u00a03 Model B+; on-board memory ranges from 256\u00c2\u00a0MB to 1\u00c2\u00a0GB RAM.Secure\u00c2\u00a0Digital\u00c2\u00a0(SD) cards are used to store the operating system and program memory in either SDHC or MicroSDHC sizes. The boards have one to four\u00c2\u00a0USB\u00c2\u00a0ports. For video output,\u00c2\u00a0HDMI\u00c2\u00a0and\u00c2\u00a0composite video\u00c2\u00a0are supported, with a standard 3.5\u00c2\u00a0mm\u00c2\u00a0tip-ring-sleeve\u00c2\u00a0jack for audio output. Lower-level output is provided by a number of\u00c2\u00a0GPIO\u00c2\u00a0pins, which support common protocols like\u00c2\u00a0I\u00c2\u00b2C. The B-models have an\u00c2\u00a08P8C\u00c2\u00a0Ethernet\u00c2\u00a0port and the Pi\u00c2\u00a03 and Pi Zero\u00c2\u00a0W have on-board\u00c2\u00a0Wi-Fi\u00c2\u00a0802.11n\u00c2\u00a0and\u00c2\u00a0Bluetooth. Prices range from US$5 to $35.<\/p>\n
The first generation (Raspberry Pi\u00c2\u00a01 Model\u00c2\u00a0B) was released in February 2012, followed by the simpler and cheaper\u00c2\u00a0Model\u00c2\u00a0A. In 2014, the Foundation released a board with an improved design,\u00c2\u00a0Raspberry Pi\u00c2\u00a01 Model\u00c2\u00a0B+. These boards are approximately credit-card sized and represent the standard\u00c2\u00a0mainline\u00c2\u00a0form-factor. Improved A+ and B+ models were released a year later. A\u00c2\u00a0“Compute Module”\u00c2\u00a0was released in April 2014 for\u00c2\u00a0embedded applications. The\u00c2\u00a0Raspberry Pi\u00c2\u00a02, which added more\u00c2\u00a0random-access memory, was released in February 2015.<\/p>\n
A\u00c2\u00a0Raspberry Pi\u00c2\u00a0Zero\u00c2\u00a0with smaller size and reduced\u00c2\u00a0input\/output\u00c2\u00a0(I\/O) and\u00c2\u00a0general-purpose input\/output\u00c2\u00a0(GPIO) capabilities was released in November 2015 for US$5. By 2017, it became the newest mainline Raspberry Pi. On 28 February 2017, the\u00c2\u00a0Raspberry Pi Zero\u00c2\u00a0W\u00c2\u00a0was launched, a version of the Zero with Wi-Fi and Bluetooth capabilities, for US$10.\u00c2\u00a0On 12 January 2018, the\u00c2\u00a0Raspberry Pi Zero\u00c2\u00a0WH\u00c2\u00a0was launched, the same version of the Zero W with pre-soldered GPIO headers.<\/p>\n
Raspberry Pi\u00c2\u00a03 Model\u00c2\u00a0B\u00c2\u00a0was released in February 2016 with a 64 bit\u00c2\u00a0quad core\u00c2\u00a0processor, on-board\u00c2\u00a0WiFi,\u00c2\u00a0Bluetooth\u00c2\u00a0and USB boot capabilities.\u00c2\u00a0On\u00c2\u00a0Pi Day\u00c2\u00a02018\u00c2\u00a0model\u00c2\u00a03B+\u00c2\u00a0appeared with a faster 1.4 GHz processor and a three times faster network based on\u00c2\u00a0gigabit Ethernet\u00c2\u00a0(300 Mbit \/ s) or 2.4 \/ 5 GHz\u00c2\u00a0dual-band\u00c2\u00a0Wi-Fi (100 Mbit \/ s).\u00c2\u00a0Other options are:\u00c2\u00a0Power over Ethernet\u00c2\u00a0(PoE),\u00c2\u00a0USB boot\u00c2\u00a0and\u00c2\u00a0network boot\u00c2\u00a0(an\u00c2\u00a0SD card\u00c2\u00a0is no longer required).<\/p>\n
