This project was originally created with the intention of the creation of a starter kit for highway, however is now bring retroactively journaled for a highway submission due to unforeseen circumstances.
I have tried to journal with accurate dates as much as possible, however I cannot guarantee they are fully true. That being said, I guarantee that the process described in this journal is accurate and actually what I went through to build this project.
I started this project at more or less zero, with my only other PCB related project being hackpad. There has been a total of 3 iterations since then.
I would like to thank @alexren for introducing me to PCB design and running the wonderful community event which inspired this project, @qwel for working with me on the original design and trying to support me however possible, and @cyao as well as @rowyn and @acon for being cool.
This project is a "smart" MP3 player capable of streaming and downloading music from wifi. It features bluetooth audio, wifi connectivity, a USB-C port, and an optional AUX jack if you don't want to use Bluetooth.

Questions
How big is the ScuffedMP3 PCB?
It measures 79.9 × 114.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ScuffedMP3 use?
38 parts, built around the ESP32-WROVER-E(4MB), DM3AT-SF-PEJM5, HS24S010B and PCM5102APW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ScuffedMP3 KiCad files?
From the DinosaurPotato534/scuffedMP3 repository on GitHub, at the commit this page was made from: the board is scuffedMP3.kicad_pcb and its schematic scuffedMP3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ScuffedMP3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask DinosaurPotato534 before reusing the design.
