Questions
How big is the Squishy PCB?
It measures 85 × 85 mm and has 4 copper layers, 1.59 mm thick.
What parts does the Squishy use?
244 parts, built around the ICE40HX8K-BG121, USB3318-CP-TR, GD25Q64EWIGR and FXL4TD245BQX. 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 Squishy KiCad files?
From the esden/squishy-hardware repository on GitHub, at the commit this page was made from: the board is release/rev1/kicad-project/squishy.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Squishy design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
