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.
