The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It's capable of doing everything you'd expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.
Developed by the Raspberry Pi Foundation in the UK, the Raspberry Pi aims to put the fun back into learning computing by promoting the study of computer science and programming at a school level.
The design is based around a Broadcom BCM2837 SoC, which includes a 1.4GHz 64-bit quad-core ARMv8 CPU processor, VideoCore IV 3D GPU, and 1GB of RAM. The design does not include a built in hard disk or solid state drive, instead relying on a microSD card for booting and long term storage. This board is intended to run Linux kernel based operating systems.
The Raspberry Pi 3 Model B+ builds upon the features of its predecessors with a new, faster processor on board to increase its speed. It also features WiFi and Bluetooth Low Energy capabilities to enhance the functionality and the ability to power more powerful devices over the USB ports.
