<description>&lt;h3&gt;SparkFun Capacitors&lt;/h3&gt;
This library contains capacitors.

&lt;br&gt;
We've spent an enormous amount of time creating and checking these footprints and parts, but it is &lt;b&gt; the end user's responsibility&lt;/b&gt; to ensure correctness and suitablity for a given componet or application.

<package name="CAP-PTH-SMALL-KIT">
<description>&lt;h3&gt;CAP-PTH-SMALL-KIT&lt;/h3&gt;
Commonly used for small ceramic capacitors. Like our 0.1uF (http://www.sparkfun.com/products/8375) or 22pF caps (http://www.sparkfun.com/products/8571).&lt;br&gt;
&lt;br&gt;
&lt;b&gt;Warning:&lt;/b&gt; This is the KIT version of this package. This package has a smaller diameter top stop mask, which doesn't cover the diameter of the pad. This means only the bottom side of the pads' copper will be exposed. You'll only be able to solder to the bottom side.</description>

<description>&lt;b&gt;DIY Modules for Arduino, Raspberry Pi, CubieBoard etc.&lt;/b&gt;
&lt;br&gt;&lt;br&gt;
The library contains a list of symbols and footprints for popular, cheap and easy-to-use electronic modules.&lt;br&gt;
The modules are intend to work with microprocessor-based platforms such as &lt;a href="http://arduino.cc"&gt;Arduino&lt;/a&gt;, &lt;a href="http://raspberrypi.org/"&gt;Raspberry Pi&lt;/a&gt;, &lt;a href="http://cubieboard.org/"&gt;CubieBoard&lt;/a&gt;, &lt;a href="http://beagleboard.org/"&gt;BeagleBone&lt;/a&gt; and many others. There are many manufacturers of the modules in the world. Almost all of them can be bought on &lt;a href="ebay.com"&gt;ebay.com&lt;/a&gt;.&lt;br&gt;
&lt;br&gt;
By using this library, you can design a PCB for devices created with usage of modules. Even if you do not need to create PCB design, you can also use the library to quickly document your work by drawing schematics of devices built by you.&lt;br&gt;
&lt;br&gt;
