Recent releases have a new CPU revision, which allows it to run faster and cooler, so you don’t need a processor fan for most loads. These have 1GB, 2GB, 4GB, and 8GB of RAM, respectively, with gigabit Ethernet, USB 3, and dual micro-HDMI ports. Built around the BCM2711 microcontroller, it comes in four versions. Launched in 2019, the Raspberry Pi 4 remains the company’s flagship. So which Raspberry Pi is right for you? We round up the whole family.

That’s been followed by a new silicon package design, squeezing Raspberry Pi 3 hardware into a new version of the tiny low-cost Raspberry Pi Zero. Recent developments have included its own silicon, the RP2040, at the heart of the Raspberry Pi Pico board, as well as custom hardware from many maker vendors. Many Raspberry Pi displays support touch, allowing you to use them to support UIs for IOT projects. If you want to use a board with a directly connected display, you have the option of using a GPIO-connected display via the device’s I2C ports or a module using the built-in display connector. Other hardware support includes a common camera connection, with several camera modules currently available, including a 12-megapixel device that works with S-mount lenses. These allow you to quickly add new features to your device, including support for Power Over Ethernet connections for remote devices. Most extensions will work on a Pi, though some key Chrome features, like history and bookmark sync, aren’t supported.Ī standard 40-pin GPIO port has allowed an ecosystem of HATs, Hardware Attached on Top boards, to develop. As there’s no 32-bit ARM build of Chrome, the main browser is the open source Chromium release. Recently upgraded to the Bullseye release, it comes bundled with coding tools and the familiar LibreOffice productivity suite. It’s now gained its own OS, a Debian-based 32-bit Linux, Raspberry Pi OS. The option of using cheap microSD cards remains popular in schools, where students can be issued with a memory card for their programs and data, sharing the more expensive single-board computers between classes. More recent devices will boot from USB-connected SSDs, with third-party cases with M.2 module supports available. This can be slow, with a risk of hitting flash write cycles on particularly heavy workloads. Most Raspberry Pis use a microSD card for storage.

Over the next decade the original ARM-based device has grown into a family of devices, including a full-blown computer, a microcontroller CPU, and a series of modules that can be used to build more complex devices. Their first device, the Raspberry Pi Model B, was launched in 2012, with 256MB of memory and a 26-pin GPIO expansion port. Inspired by the 1980s 8-bit computers that turned a generation of Britons into developers, the Raspberry Pi Foundation was set up to deliver a low-cost computer that could do the same for today’s schoolkids. There’s one brand that stands out, though: Raspberry Pi. From tiny Arduinos to NVIDIA’s AI Jetsons, they can be used for almost anything you can think of. There are a lot of single-board computers out there, aimed at makers, hobbyists and education.
