TRS connectors are the audio-style connectors that you see on some phones, MP3 players and development boards. TRS stands for "Tip, Ring, Sleeve." If you're hacking on something that has a three-conductor audio jack, being able to plug straight in will keep your build clean and simple.

Note: This plug allows you to add a custom length of wire to your connector or repair a broken shroud on an existing cable you just cannot live without. Unfortunately, the supplier has not provided a datasheet or dimensional drawing please see the similar documents provided by other SparkFun products on the "documents" tab.
