<description>&lt;h3&gt;SparkFun Electronics' preferred foot prints&lt;/h3&gt;
In this library you'll find connectors and sockets- basically anything that can be plugged into or onto.&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.

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>

<package name="AXIAL-0.3-KIT">
<description>&lt;h3&gt;AXIAL-0.3-KIT&lt;/h3&gt;

Commonly used for 1/4W through-hole resistors. 0.3" pitch between holes.&lt;br&gt;
&lt;br&gt;

&lt;b&gt;Warning:&lt;/b&gt; This is the KIT version of the AXIAL-0.3 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>
