Frequently Asked Questions

Q: What is the difference between TRS and TRRS on a 3.5mm jack?

A: A TRS (Tip-Ring-Sleeve) jack carries two audio channels — typically left and right stereo. A TRRS (Tip-Ring-Ring-Sleeve) jack adds a fourth contact, which is commonly used for a microphone channel or composite video signal. This breakout module supports the full TRRS pinout, making it versatile for headsets with built-in microphones, AV cables, and MP3 applications.

Q: Is this module compatible with Arduino or Raspberry Pi projects?

A: Yes. The module operates within low-voltage signal ranges and can be integrated into Arduino, Raspberry Pi, or other microcontroller projects where you need to interface a 3.5mm TRRS headphone jack. Simply solder wires or header pins to the breakout pads and connect them to your circuit.

Q: Does this come with soldering headers or wires?

A: The module ships as a bare SMD breakout board (quantity: 1). Header pins, jumper wires, and other accessories are not included and would need to be sourced separately depending on your project requirements.
