Questions
How big is the 40Hz S2 PCB?
It measures 59.3 × 43.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 40Hz S2 use?
15 parts, built around the CSD19531KCS. 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 40Hz S2 KiCad files?
From the tonedef/wavebox repository on GitHub, at the commit this page was made from: the board is KiCad/40Hz_S2/40Hz_S2.kicad_pcb and its schematic KiCad/40Hz_S2/40Hz_S2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 40Hz S2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask tonedef before reusing the design.
