<package name="BUZZER-12MM-KIT">
<description>&lt;h3&gt;12mm Buzzer - PTH (KIT VARIANT)&lt;/h3&gt;
&lt;p&gt;This is a small 12mm round speaker that operates around the audible 2kHz range. You can use these speakers to create simple music or user interfaces.&lt;/p&gt;
&lt;p&gt;&lt;b&gt;Warning:&lt;/b&gt; This is the KIT version of this 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.&lt;/p&gt;
