the Lord of Tools 6Pcs 3.5mm Audio Jack Breakout Board TRRS Stereo Socket Microphone Interface Module 18 * 12.5mm for MP3 Earphone

TRRS is a plug type where "T" stands for Tip, for the left channel; "R" stands for Ring, for the right channel; "R" again stands for the other ring, for the microphone or video signal; "S" stands for Sleeve, which can be used to lead out the left channel, right channel, ground wire, and plug wires. The interface part of each module is precision designed, with raised edges around the socket for easy holding and plugging. Clear markings are printed on the surface of the module to indicate the purpose of each socket, making it easy for users to distinguish and operate. The breakout board allows TRRS jacks to be easily plugged in by breaking each wire into a standard 0.1-inch pitch header. The TRRS female socket can also be used with a traditional TRS type male plug with 2 audio channels and a grounding sleeve.
