Chapter 7. Interfacing with the BeagleBone

In the last few chapters, we mostly looked at the software aspects. While the BBB can do a lot by itself, it can do a lot more when connected to other hardware. This chapter will focus on general interfacing of the BeagleBone on a low level. In the next chapter, we will look at standard expansion options on a higher level.

In this chapter, we will cover the following topics:

  • Electrical engineering in a nutshell

  • BeagleBone voltages

  • Expansion headers

  • Transistors

  • LEDs, relays, and switches

  • I2C/SPI

  • Hidden gotchas
