In this library you'll find anything that moves- switches, relays, buttons, potentiometers. Also, anything that goes on a board but isn't electrical in nature- screws, standoffs, 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.

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>
