Questions
How big is the Sound PCB?
It measures 133.6 × 74.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Sound use?
30 parts, built around the ATF22V10C-7PX, LM386 and 74HCT74D. 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 Sound KiCad files?
From the WolfNet-Computing/WolfNet-65C02-WBC repository on GitHub, at the commit this page was made from: the board is Sound/Sound.kicad_pcb and its schematic Debug/Debug.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sound design in my own project?
Its repository states no licence, so its author keeps all rights: ask WolfNet-Computing before reusing the design.
