Questions
How big is the Wasca PCB?
It measures 100 × 77.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Wasca use?
145 parts, built around the LFE5U-25F-6BG256I, RP2040, 74ALVC164245DGG:11-JSM and P25Q16SH-SSH-IR. 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 Wasca KiCad files?
From the hitomi2500/wasca repository on GitHub, at the commit this page was made from: the board is board/wasca.kicad_pcb and its schematic board/wasca.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wasca 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).
