During a clean up of my workshop, I found a selection of mystery soldering kits that I don't remember buying.

No instructions, just a board and components.

So let us build it and figure out what it does, before we turn it on.

While I was trying to figure out the schematic I found that this was a kit that was readily available and was detailed here https://projects-raspberry.com/icstation-16-music-box-diy-kit-sound-module/. So the schematic is from the website.
