Install Third-Party Software

As part of the process of setting up our environment, we will download some useful things from the
Internet that will just help to get us started and make EAGLE that much easier to use.

Installing the Adafruit and Sparkfun Libraries

You are going to load up two libraries of parts, one from Sparkfun and one from Adafruit. Although
EAGLE comes with a huge collection of parts organized into libraries, the collection of parts is so
huge that it can be very difficult to “see the wood for the trees” and find the part that you want.

However, the Adafruit and Sparkfun libraries offer simplified lists of the most common components,
and of course, they include components that the companies sell.
To download the Sparkfun library, navigate to https://github.com/sparkfun/SparkFun-Eagle-

Libraries with your browser, and select the option to download a zip file (the icon looks like a cloud
with an arrow pointing down).
Once the zip file has downloaded, the .lbr files that it contains all need to be extracted into the
.lbr folder inside your EAGLE installation folder (Figures 1-18 and 1-19).
