Have you seen the name “Raspberry Pi
” thrown around and thought to yourself, “What exactly is a Raspberry Pi?” And no, we’re not talking about a delicious dessert here.
Raspberry Pi is a series of compact, single-board computers with a range of different iterations hitting the market fairly regularly. They’re designed to promote easier tech education at home and in the classroom, and Raspberry Pi small-scale systems are available at highly competitive prices.
To keep things accessible, the systems typically cost between $25 or $35, with the $35 models offering a bit more built-in capacity and deeper functionality. Bear in mind that unless you buy a bundle of some kind, Raspberry Pi computers don’t typically ship with accessories or peripheral devices.
Let’s take a look at the history of this device, what you can accomplish with one, and much more in our comprehensive guide.
History of Raspberry Pi
Largely produced by Sony UK at their manufacturing hub
in Wales, Raspberry Pi was originally created by the non-profit Raspberry Pi Foundation. This charity is geared toward promoting tech literacy and making computing more accessible to individuals. The Foundation introduced the Raspberry Pi in 2012 and the line continues to see regular additions.
In the years since then Raspberry Pi has grown in popularity and spread all over the world. It’s also kept up with other tech trends and has integrated new features, which the Foundation’s founder, Eben Upton, wrote about in a 2018 blog post
“Just over 2 years ago, we released Raspberry Pi 3 Model B. This was our first 64-bit product, and our first product to feature integrated wireless connectivity. Since then, we’ve sold over 9 million Raspberry Pi 3 units (we’ve sold 19 million Raspberry Pis in total), which have been put to work in schools, homes, offices, and factories all over the globe.”
That’s a lot of Raspberry Pi units and nearly as many different projects. With that many users across the world, the community has grown in scope and sophistication. These days, you can find thousands of different concepts and scenarios with a thorough web search.
What can you do with a Raspberry Pi?
If you’re not already familiar with the technology, it’s easy to think “What is Raspberry Pi used for?” After all, each Raspberry Pi board is small and starts out with a seemingly small output capacity. How you approach using it is up to you. Create your own physical accessories like a colorful computer case for your board or use it as a platform for even bigger ideas.
Raspberry Pi’s low cost and vast range for customization play a big role in what makes it such an effective teaching tool. You won’t break the bank getting a starter kit and mishaps are easier to recover from.
Raspberry Pi provides a safe and low-risk way to experiment with computer technology, particularly for students and younger users. It’s easy to get started thanks to the variety of project types available, and there’s a dedicated and growing community behind it.
Small-scale projects are generally inexpensive and can involve a bit of research and DIY. If you have a bigger budget, there are tons of accessories like cases, connections, and storage that you can use to give yourself a head start. Once you get some experience, you’ll also learn about the device’s adorably-named operating system, Raspbian.
