Before we start hooking up hardware and writing code, we'll need to have an understanding of what we're working with. This chapter will introduce you to the BeagleBone and highlight the various interfaces it provides to connect to external devices. It will cover:
An overview of the BeagleBone system
An overview of the BeagleBone's peripheral interfaces, and what types of external devices each can connect to
Some additional hardware and tools that you will need if you want to duplicate the examples given throughout the book, and where you can buy them
