Questions
How big is the Tape PCB?
It measures 54 × 60.5 mm and has 2 copper layers, 1 mm thick.
What parts does the Tape use?
38 parts, built around the 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 Tape KiCad files?
From the jrowny/mixtape2 repository on GitHub, at the commit this page was made from: the board is tape.kicad_pcb and its schematic tape.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tape 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).
