The interfacing circuit used in this chapter is a combination of each of the circuits described in chapters 3, 4, and 5. If you have successfully constructed the circuits from the previous chapters, you already have a good understanding of how the circuit in this chapter will be put together. Leave any previously constructed circuits on the breadboard to save you some effort if you have constructed those circuits by closely following the instructions from earlier chapters.
The following diagram shows the connections between the sensor breakout board, FRAM breakout board, LED, pushbutton switch, resistor, and the BBB. Revisit chapters 3, 4, and 5 for the exact details on how to construct the GPIO, FRAM, and SPI portions of the circuit, if you have not yet done so.
