One truth about working with audio is you always need the cable or adapter you don’t have in your toolbox. That’s why we love these terminal-block audio connectors so much. No soldering required! Use stranded or solid core wire and a small screw driver to create custom wiring jigs.
This is the 3.5mm (1/8″) 4-Pole (TRRS) Audio Plug Terminal Block. TRRS stands for Tip, Ring, Ring, Sleeve. It has four total conductors — three signal and a ground as opposed to a more common stereo jack’s two. This connector is most often used in smartphones & cellphones to provide stereo audio and one mic channel. On a Raspberry Pi the extra connector is used for composite video
We also have a (matching) 4-Pole Audio Jack Terminal Block!
