<deviceset name="CONN_01" prefix="J" uservalue="yes">
<description>&lt;h3&gt;Single connection point. Often used as Generic Header-pin footprint for 0.1 inch spaced/style header connections&lt;/h3&gt;
&lt;p&gt;&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
On any of the 0.1 inch spaced packages, you can populate with these:
&lt;ul&gt;
&lt;li&gt;&lt;a href="https://www.sparkfun.com/products/116"&gt; Break Away Headers - Straight&lt;/a&gt; (PRT-00116)&lt;/li&gt;
&lt;li&gt;&lt;a href="https://www.sparkfun.com/products/553"&gt; Break Away Male Headers - Right Angle&lt;/a&gt; (PRT-00553)&lt;/li&gt;
&lt;li&gt;&lt;a href="https://www.sparkfun.com/products/115"&gt; Female Headers&lt;/a&gt; (PRT-00115)&lt;/li&gt;
&lt;li&gt;&lt;a href="https://www.sparkfun.com/products/117"&gt; Break Away Headers - Machine Pin&lt;/a&gt; (PRT-00117)&lt;/li&gt;
&lt;li&gt;&lt;a href="https://www.sparkfun.com/products/743"&gt; Break Away Female Headers - Swiss Machine Pin&lt;/a&gt; (PRT-00743)&lt;/li&gt;
&lt;p&gt;&lt;/p&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;/p&gt;
This device is also useful as a general connection point to wire up your design to another part of your project. Our various solder wires solder well into these plated through hole pads.
&lt;ul&gt;
&lt;li&gt;&lt;a href="https://www.sparkfun.com/products/11375"&gt; Hook-Up Wire - Assortment (Stranded, 22 AWG)&lt;/a&gt; (PRT-11375)&lt;/li&gt;
&lt;li&gt;&lt;a href="https://www.sparkfun.com/products/11367"&gt; Hook-Up Wire - Assortment (Solid Core, 22 AWG)&lt;/a&gt; (PRT-11367)&lt;/li&gt;

&lt;/ul&gt;

&lt;p&gt;&lt;/p&gt;
&lt;b&gt;Special notes:&lt;/b&gt;
&lt;p&gt; &lt;/p&gt;
SMTSO-256-ET is a "flush mount" nut for a 4-40 screw. We mostly use this on specialty testbeds; it is a nice way to connect hardware to your PCB at an adjustable hieght.
&lt;p&gt;&lt;/p&gt;
Also note, the SNAP packages are for using a snappable style connector. We sell a baggie of snaps and they are also used on two LilyPad designs:
&lt;ul&gt;
&lt;li&gt;&lt;a href="https://www.sparkfun.com/products/11347"&gt; Snap Assortment - 30 pack (male and female)&lt;/a&gt; (DEV-11347)&lt;/li&gt;
&lt;li&gt;&lt;a href="https://www.sparkfun.com/products/10941"&gt;LilyPad Arduino SimpleSnap&lt;/a&gt; (DEV-10941)&lt;/li&gt;
&lt;li&gt;&lt;a href="https://www.sparkfun.com/products/10940"&gt; LilyPad SimpleSnap Protoboard&lt;/a&gt; (DEV-10940)&lt;/li&gt;
