It’s not a fruit pie, but the Raspberry Pi is amazing in its own way. Heard a lot about this little computer, but have no idea what it’s really about? Here’s what you need to know.
Maybe small, but the Raspberry Pi is capable of a lot. This is why there is so much information about the computer and this is where things can get confusing.
We’ll help you get to grips with all things pi-flavored by looking at:
- What is Raspberry Pi? (including Pi 3 and Pi Zero)
- Where can I buy a Raspberry Pi
- Projects you can run on the Pi
- How to turn on Raspberry Pi
- How to set up the Pi
- What to do for SSH in Raspberry Pi
- How to Program on Raspberry Pi
What’s the Raspberry Pi deal?
Released in 2013, the Raspberry Pi is a credit card-sized computer originally designed to encourage the teaching of computer science in schools. Also equipped with GPIO pins and USB ports, the computer went through several iterations.
At the time of this writing, the Raspberry Pi 3 is the mainstream version, although the Raspberry Pi Zero W is also a slim alternative.
The Raspberry Pi continues the British tradition in computing: it’s built using the ARM architecture, and its ease of use to interface with other hardware is reminiscent of the Sinclair computers of the 1980s.
Projects you can do with Raspberry Pi
Its small size, low power consumption, and use of Linux operating systems (usually Raspbian) have led to the Pi being accepted as the solution to many problems.
However, it is also widely used as a media center as well as a retro gaming device. There are many ways to use the Raspberry Pi, it can be a little overwhelming.
Think of it this way: think about how flexible your desktop computer is. Then scale that flexibility down to a credit card-sized device.
The Raspberry Pi does just about everything from monitoring your network to running a print server for older printers. Oh, that was in space too: a Raspberry Pi was brought aboard the International Space Station by British astronaut Major Tim Peake in 2016.
Where can I buy a Raspberry Pi?
Millions of Raspberry Pi computers have been produced and can be purchased from many places online and offline. But if you want as soon as possible, the best place is the Amazon.
Here you can choose between a single Pi or a set with a case, cables, and a microSD card. If you choose the former, you’ll need to make sure you already have these components.
What is Raspberry Pi 3?
As noted, the current version of the computer is the Raspberry Pi 3. This device, released in 2016, has hardware that surpasses previous versions (and even the Raspberry Pi Zero). It features a 1.2GHz quad-core ARM processor, 64-bit ARM processor, 1GB of RAM (which is shared with the GPU), and built-in wireless and Bluetooth.
All Raspberry Pis require a microSD card to install the operating system, although it is possible to boot the Pi 3 from USB.
The Raspberry Pi 3 has four USB ports, an Ethernet board, and an HDMI video output. There is also a TRRS 3.5mm connector and a MIPI display interface for connecting an LCD (a touch screen device is especially suitable), as well as a MIPI camera interface for connecting a camera.
Clearly, this is a powerful little box of tricks. The hardware specification even makes the Raspberry Pi 3 ideal as a basic desktop replacement.
