PART FINDER! 3.5mm headphone jack. This part is handy if you ever want to do any audio/video projects. An inexpensive stereo 3.5mm headphone jack! This one in particular, we like a lot. First, its sturdy and easy to solder – we use it in the wave shield. There’s switches inside if you want to switch between a speaker/headphone. It’s also headphone jack that has the right spacing you can plug it into a breadboard or perfboard as is.
Best of all, we already have it in our eagle library!
