The Raspberry Pi is a series of small, affordable single-board computers developed by the Raspberry Pi Foundation in Cambridge, England. First conceived in 2006 to encourage basic computer science education in schools, the nonprofit released the original Raspberry Pi Model B in February 2012 priced at just $35 (or £25 in the UK).
Co-founder and Raspberry Pi Trading CEO Eben Upton noted that the project was motivated by declining computing skills among university applicants in the mid 2000s. By providing an accessible, low-cost computing platform for teaching coding and electronic skills especially to children, Raspberry Pi sparked a revolution in tech education.
Innovation in Cost-Effective Computing
Leveraging open-source components like Linux operating systems and ARM processors, the credit card-sized Raspberry Pi delivered capabilities exceeding most desktops from the mid-1990s, all within affordable reach for students and technology enthusiasts. Central to its mission was user-friendliness and robust educational collateral for budding coders getting started on hardware experiments.
The $35 or less price point from day one (even cheaper than many textbooks) saw Raspberry Pi achieve massive upfront demand, with Upton recalling hundreds of thousands of eager customers temporarily shutting down the product website hours after launch.
"I remember getting into the office at about five in the morning because New York had come online…by about seven o’clock lots of people had visited [the website] and we’d completely cratered. So many people hitting the site." – Eben Upton
Since 2012, newer and more powerful Raspberry Pi models have been released. The product lineup has expanded to multiple versions differentiated by computing performance, connectivity options, onboard memory, and pricing. These retain the original compact form factor but accommodate broader applications.
Massive Global Adoption, But Education Still Core Mission
According to Upton, over 40 million units have been sold globally over the past decade. He estimates a quarter are being used in industrial applications, with the remainder in homes, clubs, classrooms etc. Raspberry Pi‘s capable performance combined with cost-effectiveness has fueled its success across personal, educational, and commercial deployments.
"We set out to build for education…but we‘ve been pleasantly surprised to see them used creatively for everything from robotics to handmade video games."
While the Raspberry Pi Foundation actively works with policymakers to accelerate coding literacy via free training material, lesson plans, and affiliated programs, the hardware itself has unlocked creativity beyond formal learning environments.
Let‘s explore the core specifications, capabilities, and costs across various models over the years.
