Questions
How big is the Sampleplayer PCB?
It measures 102.7 × 76.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sampleplayer use?
65 parts, built around the PCM5102PW and SS8050. 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 Sampleplayer KiCad files?
From the kaosbeat/coatlab repository on GitHub, at the commit this page was made from: the board is modules/sampleplayer/sampleplayer.kicad_pcb and its schematic modules/passiveVCA/passiveVCA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sampleplayer design in my own project?
Its repository states no licence, so its author keeps all rights: ask kaosbeat before reusing the design.
