Questions
How big is the Audio player PCB?
It measures 74 × 63.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Audio player use?
87 parts, built around the RP2040, 74LVC1G125, MAX98357AETE+T and W25Q128JVSIQ. 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 Audio player KiCad files?
From the Vaaarad07/PCB_Designs repository on GitHub, at the commit this page was made from: the board is RP2040/Audio_player.kicad_pcb and its schematic Cyclometer/Cyclometer_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio player design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
