Audio Cable TRRS - 18" (pigtail)

TRRS connectors are the 3.5mm 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) If you're hacking on something that has a 4-conductor audio jack, being able to plug straight in will keep your build clean and simple.

Connectors are a major source of confusion for people just beginning electronics. The number of different options, terms, and names of connectors can make selecting one, or finding the one you need, daunting. This article will help you get a jump on the world of connectors.

    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.

    Is the CAB-11580, TRRS cable male to pigtail product available with a longer cable length? Thanks!

    What gauge wire is inside this?

    We need the matching jack!!! Please Please Please

    Ok, so that level of excitement may not be warranted here... But finally! A 4-pole jack! I've been dying to incorporate some USB-to-3.5mm cables in some of my projects - using one port on the pcb which can be used for both audio and serial RX/TX comm. Any chance on stocking the 4 conductor female receptor as well? THX U SF!

    I had an old ipod shuffle which use this connection for charging and usb transfer and wanted to show some photos I had stored on the device to some mates.

    We ended up using a 3 component video to TRRS cable in combination with a dissected old usb cable and some clothes pegs to produce a "I can't believe that worked" reaction from those at the place. Classic.

    Found this helpful pin-out guide.

    A cable terminated with RCA Video and standard stereo audio on one end and the TRRS on the other would be most useful for RPi B+ owners. Is there such an animal?

    • Mitchell.Spanheimer / about 7 years ago / 1

      Yes there is a lot of digital cameras that use the same type of cable to connect to a TV, but I'm pretty sure Sparkfun doesn't sell one. You would have to google it, or you could probably find one on Amazon or Ebay

  • Member #297571 / about 10 years ago / 1

    A double sided version of this would be perfect for connecting a Raspberry Pi B+ to a car DVD player.

    Got a defective one whose microphone line died during a job interview. Not much quality control with these. At least get a microphone monitoring app for the phone. My only other issue is 18" is too short. It should be at least as long as a headphone cable.

  • Bubblehead / about 12 years ago / 1

    I need the board mount jack too so I can use it for VCC, GND, TX, RX for a shifter and datalogger I use. This would make it very easy to install.

    • Member #151461 / about 12 years ago / 1

      Any luck finding a board mount for this. I am also looking for some.

  • Yay! No more mono audio out of my phone! Thanks Sparkfun, this is a great product!

    This appears not to be shielded, looking at the closeup and the pinout diagram. Or is the ground wire tied to a shield that just doesn't show well on the closeup? Can anyone confirm?

    • chartle / about 12 years ago / 1

      It doesn't look like its shielded and I think it would be on the pin out. For me that would be a good thing because I just want a 4 con plug and don't care about shielding since it kind of gets in the way.

  • chartle / about 12 years ago * / 1

    I asked about this a few months ago. I have a few projects that need 4 conductors. :-)

    Is there a matching jack in the works? Inline would be best.

    • Member #387818 / about 11 years ago / 1

      ask at any local audio shops, they sometimes have connectors (male and female) on sale or a lead they've already hacked up and they have left overs. Your most likely to find the old 3 poles but might find a 4 pole.

    • you can find cheap extension cables on ebay, just cut them in two

      • chartle / about 12 years ago / 1

        Yes but sometimes they use really thin wires and maybe not that hacker friendly.
