<description>&lt;h3&gt;Reference foot prints for Particle devices&lt;/h3&gt;
In this library you'll find foot prints to make circuit boards using the Particle devices: Spark Core, Photon and Electron.&lt;br&gt;&lt;br&gt;
There are for reference and you may need to adjust them for your application. See https://docs.particle.io for more details on the recommended layouts for Particle devices.

<description>&lt;h3&gt;SparkFun Electronics' Retired foot prints&lt;/h3&gt;
In this library you'll find all manner of retired footprints for resistors, capacitors, board names, ICs, etc., that are &lt;b&gt; no longer used&lt;/b&gt; in our catalog.
&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. 
&lt;br&gt;
&lt;br&gt;If you enjoy using this library, please buy one of our products at &lt;a href=" www.sparkfun.com"&gt;SparkFun.com&lt;/a&gt;.

You are welcome to use this library for commercial purposes. For attribution, we ask that when you begin to sell your device using our footprint, you email us with a link to the product being sold. We want bragging rights that we helped (in a very small part) to create your 8th world wonder. We would like the opportunity to feature your device on our homepage.</description>
