Using Capes and Modules
As you saw in Chapter 7, it is perfectly possible to make you own electronics on a breadboard and attach it to a BeagleBone Black using jumper wires. You can also use ready-made “capes” that plug onto the GPIO headers, or you can use other separate electronic modules that are suitable for connecting to the BeagleBone Black.
The range of capes is always expanding, so this chapter only surveys a few of the current capes. Be careful, because some of the capes available for BeagleBone are not compatible with the newer BeagleBone Black model. Therefore, be sure to check this before you buy. A list of capes and their compatibility with BeagleBone Black can be found at http://elinux.org/Beagleboard:BeagleBone_Capes.
