What is a Raspberry Pi?

Raspberry Pi’s are mini-computers that you can fit in your hand but still have large amounts of processing power. 

They can be used for many things, from a server to even a home computer, as they are highly versatile and surprisingly cheap, only around £35 at the time of writing this in 2022.

Fun fact!

Believe it or not, even a Raspberry Pi Zero – 30mm by 60mm – is more powerful than the computers that took humans to the moon!

Operating system

A Raspberry Pi runs on Raspberry Pi OS (previously called Raspbian), a Linux Distribution. That means many valuable programs come preinstalled. You can even install other Operating Systems.

A Raspberry Pi comes with many ports depending on the model, usually including USB c or mini for power, USB 2.0 and 3.0 for data, HDMI or HDMI mini for video and a CSI port for cameras, a DSI port for more video, a headphone jack for audio, GPIO (General Purpose Input Output) Pins for other connections and finally an SD card port for the primary storage card.

They are also great for just about any project that needs a little more power than an Arduino as – unlike Arduinos, which just runs a modified c++ – it can run almost any language as long as you have its comPiler. They can also interact with virtually any peripheral that can be connected, and even if it can’t, you can just hook it up to the GPIO and have some code parse the signal.

Raspberry Pis are also surprisingly cheap depending on the model, ranging from the 8GB RPi 4 being the most expensive to the above RPi Zero being the most affordable. Despite this, they are all great value as the £56 price tag for the 8GB RPi 4 makes sense as there is 8GB of ram, a CPU comparable to slightly older Intel CPUs, loads of ports, WiFi support, Bluetooth support, Upgradeable storage (even iPhones don’t do that!)

Because of their high ram/computing power to size ratio, they can be easily fitted into small projects or be connected to racks to increase their processing power which can be helpful when running a server or a simulation.

Raspberry Pis are also great as a home computer as they have a pretty good CPU, 8GB of ram and second screen capability, making them better than some PCs. Again because of their small size, they can easily be hidden or built into a desk to make some nice-looking setups. The downside to doing this, though, is that you cant have an upgradeable GPU, have no way to increase RAM and are usually limited to 4 USB ports, all of which make them quite the wrong choice for playing games.

Raspberry Pis are an excellent choice for anything from a small project to a small personal computer between their low price, small size, high power and enormous amounts of versatility. If you need a robust controller for a project, there’s a good chance a Raspberry Pi is perfect!
