Raspberry Pi is a series of small, affordable single-board computers developed by the Raspberry Pi Foundation in the United Kingdom. The first Raspberry Pi was released in February 2012, and since then, the Foundation has released several models with improved hardware and capabilities. The Raspberry Pi is designed as a low-cost computer that is accessible to anyone, with a focus on education and learning. It can be used for a variety of projects, from programming and coding to building DIY devices and robotics. Its low cost and ease of use make it an excellent choice for educators, hobbyists, and tinkerers.
