<description>&lt;h3&gt;SparkFun Electronics' preferred foot prints&lt;/h3&gt;
In this library you'll find all manner of digital ICs- microcontrollers, memory chips, logic chips, FPGAs, etc.&lt;br&gt;&lt;br&gt;
We've spent an enormous amount of time creating and checking these footprints and parts, but it is the end user's responsibility to ensure correctness and suitablity for a given componet or application. If you enjoy using this library, please buy one of our products at www.sparkfun.com.
