So... I'm an idiot.
For Audio Output Switch
I bought the kit, assembled and hooked it up... only to find it didn't do as I expected it to... because I can't read lol
I thought this could switch between audio INPUTS.. even though it is clearly labeled an OUTPUT switch lol.
Once I set it up as intended, it worked like a charm!
Great little project for those learning to solder!
What's also cool is it serves as a great drop in for larger projects, thou it did not work in mine for the above reason of my brain did a dumb. Still, the board fit, and all connections worked as expected in a nice small package.
Not to mention communication with the seller, I reached out to him with my issue, and he was able to infer and remedy my mistake instantly.
Will buy again, and definitely will buy from the seller again!
