Here is a brief overview of each of those elements. But whats sets one apart from the rest? What makes a good SD card? Besides manufacture, the main differences between cards are physical size, capacity/standards, and speed. SD Cards can be found most everywhere, online, at your local store.
However, you may find these links useful in your SBC adventure. There is no one best place to start when it comes to single board computers. Last, you'll want your SBC or whatever device into which you are installing your card. You will also need a computer and an Internet connection (if you don't have all the software and your image already on your computer). Make sure to check the image distribution that you are planning on using for your Single Board Computer before flashing. The minimum card size depends on the Linux distribution. To follow along with this tutorial, you will need an SD card, and a card reader (see related sections for more information on different types). Pictured here: a microSD card with full-size adapter. Single Board Computers, such as the Raspberry Pi, use SD and microSD cards to house various operating systems.
