<description>&lt;h3&gt;SparkFun Jumpers&lt;/h3&gt;
In this library you'll find jumpers, or other semipermanent means of changing current paths. The least permanent form is the solder jumper. These can be changed by adding, removing, or moving solder. In cases that are less likely to be changed we have jumpers that are connected with traces. These can be cut with a razor, or reconnected with solder. Reference designator JP.
