This is a foot-long white audio cable that has been terminated with two TRRS connectors at each end. 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 (as in hands-free headsets) or to carry a video signal (as 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. https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2017-05-05 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2017-11-24 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2017-11-28 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2018-05-05 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2018-11-21 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2018-11-27 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2022-02-21 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2025-04-07 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2025-04-10 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2025-04-12 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2025-04-14 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2025-06-17 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2025-06-19 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2025-07-15 https://elecena.pl/product/8341115/audio-cable-trrs-1ft 2025-07-17
