Questions
How big is the Shoyu PCB?
It measures 115.6 × 54 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Shoyu use?
64 parts, built around the TPA3255DDVR. 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 Shoyu KiCad files?
From the ArnavMK/WaveForge repository on GitHub, at the commit this page was made from: the board is Hardware/shoyu/shoyu.kicad_pcb and its schematic Hardware/Gen/gen.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shoyu design in my own project?
Its repository states no licence, so its author keeps all rights: ask ArnavMK before reusing the design.
