History and Development
The Raspberry Pi Foundation, a UK-based charity, was established in 2009 by Eben Upton, Rob
Mullins, Jack Lang, and Alan Mycroft. The founders were motivated by the decline in computer science skills among students and envisioned a device that could reignite interest in
programming and electronics.
The first iteration of the Raspberry Pi, known as the Model B, was released in February 2012.
This pioneering device featured a Broadcom BCM2835 system on a chip (SoC) with an
ARM1176JZF-S 700 MHz processor, 256 MB of RAM, and could run a variety of operating
systems, including Linux and RISC OS. Its launch marked a significant milestone in computing
education, providing an affordable platform for students and educators.
The Foundation has since developed several iterations of the Raspberry Pi, each iteration
improving upon its predecessor in terms of performance, memory, and connectivity. The
models include the Raspberry Pi Model A, B+, 2, 3, 4, and the Zero series, catering to different
needs and budgets. Each new model brought enhancements that expanded the possibilities of
what users could achieve with their Raspberry Pi.
