Ampersound is a DIY MP3 Player with capacitive touch controls, USB C charging, and a small built-in speaker.
It uses a Pro Micro to drive the controls and screen, and a DFPlayer mini for playback.

It includes the arduino code; Eagle PCB library, schematics, and gerbers; STLs and Solidworks files for the case; the build guide; bill of materials; and some extras.

Feel free to modify/improve/expand anything provided here. I hope it helps someone get started with PCB design.
