In February 2016, Raspberry Pi 3 Model B was launched, which is currently the main product available.

In 2015, the Foundation revolutionised the design of the board by releasing a small form factor edition costing US$ 5 (about ` 323) called Raspberry Pi Zero. In 2014, the Foundation released a significant and improved version of the board -Raspberry Pi 1 Model B+. The first version was Raspberry Pi 1 Model B, which was followed by a simple and cheap Model A. Over the years, the Raspberry Pi Foundation has released a few different versions of the Pi board. It requires just a 5V micro-USB power supply, similar to the one used to charge a mobile phone.

Its credit-card-like size makes it extremely portable and affordable.

It contains ports like HDMI (High Definition Multimedia Interface) to provide users with video output. Raspberry Pi has USB sockets, which support various peripheral plug-and-play devices like the keyboard, the mouse, the printer, etc.

Raspberry Pi, a small development board minicomputer that runs the Linux operating system, was developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer science in schools in the UK and in developing countries. Currently, it has gained popularity much beyond its target market and is being used in robotics projects. It has also turned out to be a boon for software developers. The Raspberry Pi, a tiny single-board computer, has revolutionised the way in which computer science is being taught in schools. Raspberry Pi has a wide range of IDEs that provide programmers with good interfaces to develop source code, applications and system programs.
