Cable for easy In-Circuit Serial Programming. Designed for Microchip ICD2, suitable for many others.
&lt;p&gt;
&lt;b&gt;NOTE:&lt;/b&gt; Eagle's default spacing for drill holes does not leave sufficent room for routing traces for this footprint and should be adjusted. &lt;br&gt;
This setting can be found in the board layout editor under the Edit menu.  Select "Design Rules" and then the Distance tab.  8 mils for Drill/Hole works well.
