Raspberry Pi Explained: What Is It and How Can I Use It for My Home’s Internet Connection?

A Raspberry Pi computer can do a little of everything and keep you occupied if you need a new project. This teeny-tiny computer not only clocks in at a low price, but could potentially help you trim costs by becoming a DIY router. Saving money is particularly appealing now: A recent CNET survey showed that internet costs spiked for 63% of US adults last year. When our budgets are tight, having a device that can cover the gamut is appealing, from hosting your home internet to providing a platform for your next gaming experience. What was once a simple tool for teaching students about computers has become a fun tech experience for computer lovers everywhere.

What is Raspberry Pi?

Raspberry Pi is a tiny, inexpensive computer about the size of a credit card. It was initially developed in the UK to teach school kids about computer science. As the single-board computer has become more popular over the years, people everywhere have used it for various projects. It has evolved into newer, better versions with Bluetooth and Wi-Fi capabilities, and its price has kept falling. 

Raspberry Pi computers don’t have hard drives (they don’t have much at all), but that’s why they’re great starting points for those who want a project. They have ports so you can plug in a monitor and keyboard, as well as a microSD card, and once you’ve installed an operating system, you can use the Raspberry Pi as a full-fledged desktop computer.

The Raspberry Pi 5 is the most recent iteration, with the 16GB model launching in January 2025. It has a 2.4GHz quad-core 64-bit ARM Cortex-A76 CPU and a VideoCore VII GPU, a significant upgrade from the Pi 4. It’s also available in 2GB, 4GB and 8GB, with prices ranging from $50 to $120.

The Raspberry Pi Zero is the most minimal model, retailing for only a few dollars. While it can still run many of the same functions as the other Pis, it doesn’t run nearly as smoothly (or as quickly) as the ones with more RAM. 

What is Raspberry Pi mostly used for?

Raspberry Pi isn’t most people’s first choice for a desktop computer. You’re most likely getting this computer if you want to tinker with it or have another project in mind. However, a Raspberry Pi can function as your primary computer, if that’s your choice. 

Popular ways people use their Raspberry Pi include as gaming consoles, running their smart devices and as internet routers. In terms of gaming, one option is to configure your Pi for throwback games with RetroPie, an open-source software that works with any Raspberry Pi. 

You can also link up with your smart devices to control your lighting, TVs and more with your Pi. You can also use it as a router for home internet (more on that later). The capabilities of this tiny computer are endless, and a quick Google search will turn up even more ideas you can do with it.

Why would I use a Raspberry Pi?

Many people use Raspberry Pi computers because they enjoy the thrill of building a computer and like the uniqueness of what Raspberry Pi provides. Truthfully, there is no specific reason to use a Raspberry Pi computer versus any other computer or machine. Various other devices exist in much the same way. It is often about the novelty that this one provides. 

If you surf through the Raspberry Pi subreddit or the Raspberry Pi Forums — both of which are packed full of Raspberry Pi folks, from novices to pros — you’ll find thread after thread of people discussing their Raspberry Pi projects, big and small. Within the discussions, they’ll compare notes on how they’re using the pocket-sized computer, why they’re doing it, asking for help and more.

All of that’s to say, you often use a Raspberry Pi computer because it’s fun and a challenge. It was originally created as a teaching tool, and it continues to be a great learning device for anyone who wants to understand more about computers without breaking the bank. Plus, you can do some cool things with them.

Is it safe to use a Raspberry Pi?

Regarding security, a Raspberry Pi computer is relatively safe, though it has risks. Then again, so does any desktop or laptop. Where you run into some trouble with a Raspberry Pi is the Linux operating system it runs on, because it uses a microSD card. That leaves your computer a bit vulnerable (though the open-source Linux is quite solid and many prefer it to any other OS) because someone could simply walk away with the microSD card, as this DZone report points out.

You can ensure your Raspberry Pi is more secure internally and physically by encrypting the device and making it more difficult to steal your information. It’s highly recommended that you do this (much like you’d do with any computer to prevent hacking or data breach), but, in general, a Raspberry Pi computer is no more vulnerable than other computers.

How could using a Raspberry Pi help my home internet network?

Your Raspberry Pi can be used as a router on your home network, though admittedly, the Pi is better equipped to handle smaller networks. Some Raspberry Pi users have found more success as a travel router because it functions better as a Wi-Fi tool or hotspot in small use cases.

But don’t worry, you can still use it at home for your internet. There are a few handy guides to set up your Pi for internet access at home. These will essentially walk you through the process of ensuring your Pi is up to date, has the right software and can bridge between networks. This guide on Medium turns your Raspberry Pi into a Wi-Fi router, and this Raspberry Pi YouTube video shows you how to add Ethernet to your Pi. Finally, a Raspberry Pi 5 can also be turned into a Wi-Fi extender using this handy guide.
