Adafruit 3.5mm Mono Headphone Jack Breadboard-Friendly Vertical

SKU CH-X19A-SNCRT

A breadboard-friendly 3.5 mm mono audio jack with a disconnect pin for prototyping audio connections

  • TypePrototyping Products
  • Breadboard-ready vertical layout with .1 pin spacing
  • Mono 3.5 mm jack accepts standard audio cables
  • Disconnect pin signals when a plug is inserted
  • Solder into perf-board for reliable mechanical strength
  • Routes ground, tip and switched pins for simple audio I/O

Breadboard-Friendly Mono Audio Jack

This vertical 3.5 mm mono headphone jack plugs directly into a solderless breadboard or perf-board on .1 inch pin spacing. It provides a ground sleeve pin, a left tip pin and a disconnect pin that opens when a cable is inserted. Any standard 3.5 mm audio cable can be used with the connector. The jack is supplied new and works best when soldered into a perf-board for a permanent connection.

Suitable for Prototyping Audio Interfaces

Makers and students who need a quick way to pipe mono audio in or out of a microcontroller project will find this jack convenient for breadboard experiments. It is not suited for builders who require stereo output or a panel-mount connector for enclosure integration. The part also lacks an integrated cable, so users must supply their own 3.5 mm lead. Projects needing a ruggedised or waterproof audio interface should look elsewhere.

Fits Standard .1 Inch Prototyping Grids

The vertical pin arrangement lets the jack sit upright on a breadboard, freeing horizontal space for other components while keeping the audio socket accessible. Soldering the pins into a perf-board creates a mechanically secure joint that withstands repeated cable insertion and removal. No additional mounting hardware is required beyond the prototyping board itself, and the disconnect pin can be wired to detect when a plug is present.

Otázky k tomuto produktu

What spacing do the pins need on my breadboard for the 3.5mm jack?

The pins sit on .1 spacing, so they fit standard solderless breadboards, perma-proto boards and perf-boards.

Will the mono jack accept the stereo cable I already use?

Yes, any 3.5mm audio cable plugs in; the ring contact simply connects to the same tip pin because the jack is mono.

How can I confirm the disconnect pin switches when I insert a plug?

With no cable inserted the disconnect pin is connected to the tip pin; plugging in a 3.5mm cable breaks that connection, which you can verify with a multimeter.
