The Raspberry Pi, a series of compact single-board computers, was created in the UK by the Raspberry Pi Foundation and Broadcom. Initially aimed at promoting computer science education in schools, it gained unexpected popularity beyond its target market. Its affordability, adaptability, open design, and compatibility with HDMI and USB standards made it a favorite among hobbyists, robotics enthusiasts, and for applications in home and industrial automation.
The Raspberry Pi's video controller was capable of outputting a range of resolutions, from older CRT TV standards to modern HDTV resolutions like 1080p. However, maximum resolution support didn't guarantee the GPU could decode video formats at those resolutions.
The Raspberry Pi's design draws inspiration from Acorn's BBC Micro, released in 1981. The naming convention for the Raspberry Pi models, specifically the Model A, Model B, and Model B+, is a direct homage to the original models of the BBC Micro, a British educational computer developed by Acorn Computers.
The first-generation Raspberry Pi, while operating at 700 MHz, offered performance comparable to a 300 MHz Pentium II processor from the 1997-1999 era.
The initial concepts for the Raspberry Pi began to take shape in 2006, with the design initially centered around the Atmel ATmega644 microcontroller. In a move towards transparency, the schematics and PCB layout were made available to the public. Eben Upton, a trustee of the Foundation, assembled a team of educators, academics, and computer enthusiasts to develop a computer capable of inspiring children's interest in technology.
By January 2012, Raspberry Pi had garnered significant interest from schools in the UK, with private schools showing a higher level of engagement. There were hopes for businesses to sponsor the technology for less privileged schools. Notably, a Middle Eastern government expressed interest in providing every schoolgirl with a board to improve their future employment opportunities.
The Raspberry Pi project took a significant step in February 2012 by starting to accept orders for the Model B, the higher-priced version at $35. This marked the beginning of the Raspberry Pi's journey to becoming widely available.
The Raspberry Pi Model B with 512 MB RAM was released in October 2012. Initially using separate memory split files, a week later, a new start.elf file enabled dynamic RAM allocation for the GPU through a config.txt entry, simplifying memory management.
The Raspberry Pi won T3's Innovation of the Year award in October 2012. The same month, the British Computer Society expressed interest in the Raspberry Pi following the announcement of enhanced specifications.
