Questions
How big is the MY MP3 PCB?
It measures 32 × 57.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MY MP3 use?
85 parts, built around the VS1053B-L, AP7312-1833W6, RT9080-33GJ5 and ESD5Z3.3T. 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 MY MP3 KiCad files?
From the myk-src/MY-MP3 repository on GitHub, at the commit this page was made from: the board is MY-MP3.kicad_pcb and its schematic MY-MP3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MY MP3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask myk-src before reusing the design.
