Questions
How big is the Stylophone PCB?
It measures 87 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stylophone use?
80 parts, built around the TPM8837C-SO1R, 74HC74D and MCP6489-E/SL. 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 Stylophone KiCad files?
From the VikeshSubra/FreesideElectronics repository on GitHub, at the commit this page was made from: the board is Stylophone/Stylophone/Stylophone.kicad_pcb and its schematic Stylophone/Stylophone/Stylophone.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stylophone design in my own project?
Its repository states no licence, so its author keeps all rights: ask VikeshSubra before reusing the design.
