I would like to attach a headphone jack to this board but I'm a bit confused as to how since the jacks I find have 5 pins but this only has 2 places for the headphone cables.

Thank you in advance for your help!

  • \$\begingroup\$ With a single LM386 you only get mono. So connect the pin labelled Out+ (or whatever) to both tip and ring on the connector, and Out- (or 0V or Ground) to the sleeve. And ignore the other two contacts, they are switches. If you want to wire up a speaker, you can wire it to either of them : then the speaker will be disconnected when you plug the headphones in. \$\endgroup\$

  • \$\begingroup\$ @BrianDrummond so being mono will it play in both ears of the headphone or only one? Sorry I'm new to this and trying to learn \$\endgroup\$ Commented Jun 19, 2016 at 15:07
  • \$\begingroup\$ The tip of the plug will connect to one ear (left. I think), and the ring to the other ear. The sleeve of the plug will be common to both ears. Brian suggests connecting the amplifier output "hot" side to tip and ring, to drive both ears. \$\endgroup\$ Commented Jun 19, 2016 at 15:45

On the connectors that you've pasted, they're probably 5 pinned for other reason, which may be for a better holding to PCB. Not all pins are always functional only for signals or voltage/current transmit.

On the other side, this module is for mono output only. It means, you can only listen to either left either right speaker.

How to connect? See on picture, but for connector, measure pins for sure!
