<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;
The latest version, examples, photos and much more can be found at: &lt;b&gt;&lt;a href="http://diymodules.org/eagle"&gt;diymodules.org/eagle&lt;/a&gt;&lt;/b&gt;&lt;br&gt;&lt;br&gt;
