<description>&lt;h3&gt;SparkFun Electronics' preferred foot prints&lt;/h3&gt;
This library contains footprints for SparkFun breakout boards, microcontrollers (Arduino, Particle, Teensy, etc.),  breadboards, non-RF modules, 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 &lt;b&gt; the end user's responsibility&lt;/b&gt; to ensure correctness and suitablity for a given componet or application.
