Many cases (Opens in a new window) also come with separate heatsinks and/or fans, which can aid in keeping that system-on-a-chip running cool. Of course, there are other cool cases out there, like retro gaming cases (Opens in a new window) and transparent cases (Opens in a new window) that show off the hardware inside. Pi 4 cases are still coming to market, but for earlier models, the FLIRC case (Opens in a new window) is a particularly great option thanks to its built-in heatsink. Instead of having your bare board out in the open, it's probably a good idea to protect it with a case. Technically, this is optional but we recommend it. You'll also need a way to plug the SD card into your computer, like this USB adapter (Opens in a new window). Not all SD cards work perfectly, though, so your best bet is to either buy the official Raspberry Pi microSD card (Opens in a new window) (which comes with an operating system preloaded) or a tested compatible one from this list (Opens in a new window), like the SanDisk 32GB Ultra (Opens in a new window). Most newer Pi models use microSD cards for storage, with the original Pi model A and B using a regular SD card. The USB chargers you have lying around might not provide consistent enough power to the board, and the less you have to troubleshoot, the better. While certain phone chargers might power the Pi just fine, I recommend buying a power adapter designed for the Pi like this one from CanaKit (Opens in a new window) or the official models (Opens in a new window) from the Raspberry Pi Foundation. Previous versions of the Pi use microUSB for power delivery, but the Raspberry Pi 4 upgrades to USB-C (albeit an out-of-spec version). Earlier models like the Raspberry Pi 3 B+ (Opens in a new window) ($192.50 at Amazon) (Opens in a new window) and Raspberry Pi 2 ($89.99 at Amazon) (Opens in a new window) are also for sale on Amazon, as is the Raspberry Pi Zero (Opens in a new window), which packs a bit less power into an even tinier package. The latest model is a bit tough to find since it's in such high demand, but you can check this approved list of resellers (Opens in a new window) to see where it might be available. To get your project up and running you'll need a few things: The Raspberry Pi The Raspberry Pi is the heart of your project, but a single circuit board isn't going to go very far without a power supply or storage. These older models produce less heat, which is a nice feature if your project doesn't require much power. The latest Pi, at the time of this writing, is the Raspberry Pi 4 ($189.95 at Amazon) (Opens in a new window), which rocks a 1.5GHz quad-core ARM CPU, a 500MHz VideoCore VI GPU, and 1GB of RAM-though you can step up to 4GB of RAM for a bit more money.Įarlier models are still available for $35, but you can often find used models a bit cheaper than the list price. Since its inception, many models of the Pi have been released, some with multiple revisions (like the Raspberry Pi 3 Model B+, which improved the previous Model B's networking capabilities). The nonprofit Raspberry Pi Foundation originally designed the Pi as an inexpensive computer for teaching programming, but it quickly became popular among DIYers looking for a more powerful brain in their electronics projects. The Raspberry Pi is small, doesn't use much power, and is relatively inexpensive at just $35. It doesn't have onboard storage, but it has an SD card slot you can use to house your operating system and files. It uses what's called a system on a chip (Opens in a new window), which integrates the CPU and GPU in a single integrated circuit, with the RAM, USB ports, and other components soldered onto the board for an all-in-one package. The Raspberry Pi (Opens in a new window) is a tiny computer about the size of a deck of cards. If you're building something with the Pi, start here. The Raspberry Pi is a dream machine for all kinds of projects-gaming consoles, home streaming, VPN servers, and beyond-but the first step is gathering up your supplies and learning the basics. Six years ago, a single-board computer came on the market and changed the game for tinkerers and DIYers.
