This part of the chapter deals with how you can build a media player for yourself using the concept of capes, which you've just been introduced to. From the long list of available capes, we'll use the BeagleBone Black Expansion board from Chipsee.
From the two versions of this expansion board—resistive and capacitive—we will use the capacitive version, which has a five-point multitouch.
If you take a look at the functionalities that this expansion board proposes, it will give you an idea of why this is more than a display:
A 7-inch screen with a resolution of 1024 x 600 pixels
Capable of 5-point detection
One audio out and one mic in
Two RS232 ports
One RS485 port
Two analog channels
1 CAN port
1 integrated buzzer
Five user keys
Two user LEDs (green and blue)
One embedded 3-axis accelerometer
