SparkFun TRRS 3.5mm Jack Breakout

TRRS connectors are the audio-style connectors that you see on some phones, MP3 players and development boards. TRRS stands for "Tip, Ring, Ring, Sleeve," which reflects the fact that, unlike a standard stereo connector, this actually has three conductors and a ground. Some devices use the extra conductor for a microphone (like hands-free headsets) or to carry a video signal (like in some MP3/MP4 players). This breakout board makes it easy to add a TRRS jack to your prototype or project by breaking out each conductor to a standard 0.1" spaced header.

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

    Just in case someone else is needing to interface to "standard" earbud/microphone sets, I'll share what I tracked down in the way of specs: from the plug (earbuds) side and from the jack (phone) side.

    Great, any reason you are not selling the connector without the breakout board ?

    Screw holes? Where are the screw holes!?! Gah! The lack of screw holes makes it so much harder to use these things in projects (well, my kind of projects). Please please please add screw holes to any breakout...please!

    Will this work with a Tip and Sleeve plug?

  • a2304 / about 11 years ago / 1

    The connector only is PRT-12639

  • softex / about 11 years ago / 1

    This connector would be great where space is at a premium. Would like to buy some of these w/o breakout. How about it?

  • How do I hook this up to an arduino for FFT and spectrum analysis

      Answering this for people who are looking :P

      Arduino FHT can provide you a quick solution for frequency analysis:

  • What is the part number for the connector on this board? I'd like to find out more information on it. Is a datasheet available?

    With a vast supply of cheep ipod shuffle cables out there this would be a slightly noisier but more robust usb connector for a project.

  • Member #392189 / about 12 years ago / 1

    It's not quite clear in the photo if the center of the headers are hollow or if they are metal contacts. Can someone please clear this up for me. Thanks!

Good product

Works great as expected

As expected

Nice little unit! I soldered it into place without incident. Maybe I'll get to plug the earbuds into it and detect nuclear decay from my newly built bGeigie Nano Geiger counter.

Works perfectly!

This is exactly what I needed and works great! I'm glad that it is a 4 pin connector so I can fully use my headset!

So far so good

This is the only 4 pin 3.5mm headphone jack breakout we could find anywhere online and its working great.

Simple, effective and high quality

ordered them for final prototyping before soldering direct... this is a pretty basic product, well made and worked flawlessly. not much to say other than it's a high quality jack (nice tight pressure in the jack) and breakout board.

If you are using with RasPI and GPIO you need to pay attention exactly how you plan your connections.... Not putting your connections in the right order, based on your pin out plan can be the different between being able to Hot Swap 1Wire sensors and causing a reboot due to shorting the pins as you plug it in......
