Some of the best DIY projects use microcontrollers or cheap single board computers to automate awesome stuff. But Between the Arduino, the Raspberry Pi, and the BeagleBone, it’s hard to figure out which is best for a project. Let’s demystify the most popular boards and make the selection process a bit easier.
Advantages: At $25, the Arduino is cheap enough that you can buy a few to mess around with. Alongside the flagship Arduino Uno, you have a ton of other variations of the Arduino to choose from. The Arduino also consumes very little power, so it’s perfect for projects that run all day long, or need to be powered with batteries. Most importantly, the Arduino is insanely popular, so it’s easy to find support, tutorials, and projects. Finally, the Arduino is flexible and can interface with just about anything.
Disadvantages: The Arduino is a beginner board, but it still takes a little while to get used to using something without a graphic interface. Because it’s cheap and small, the Arduino can’t usually handle a lot of different processes at once, so it’s not good for projects that are incredibly complicated or require a lot of computing power.
Raspberry Pi –
Advantages: Around $30 only, also being a tiny computer comes with all kinds of advantages. For one, the Raspberry Pi’s HDMI port means it’s easy to plug into a TV, and the two USB ports make it so you can operate it like a computer with a mouse and keyboard easily. It also has an ethernet port built in, so you can easily connect to the internet with little hassle. Since the operating system runs off a SD card, you can also change operating systems easily by simply swapping out the card. This is pretty handy considering you have a few options for the operating system. For the price, the Raspberry Pi is powerful but still easy enough for beginners to use.
Disadvantages: The Raspberry Pi is awesome for just about any project you’d use a computer for, but unlike the Arduino and BeagleBone, it doesn’t have as many options to interface with external sensors or buttons. So if you want to do a project that’s interfacing with other electronics in your home, or lights around the house, the Raspberry Pi isn’t quite as solid of an option.
Advantages: The BeagleBone comes packed with flash memory and an operating system already installed, which means that out of the box it’s already fully operational. If you want to run in headless mode (without a monitor), it’s easy to do, and you don’t need extra hardware to set it up like you would with the Raspberry Pi. The big advantage for the BeagleBone is that it has a really good set of input/output features (69 GPIO pins compared to the Raspberry Pi’s eight) so it can interface with exterior electronics easily.
Disadvantages: The BeagleBone doesn’t have as many USB ports as the Raspberry Pi, nor does it have video encoding built in, so it’s not really that great as a standalone computer or entertainment system. It also doesn’t have quite the same amount of fervor around it as the Raspberry Pi, so while the community around the BeagleBone is strong, it’s not nearly as loud as the Raspberry Pi. That means tutorials and project ideas are a little harder to come by.
