Questions
How big is the Mask-2.0.0 PCB?
It measures 307.3 × 148.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mask-2.0.0 use?
161 parts, built around the RP2040, W25Q128JVPIQ, AP2112K-3.3 and 1N4148W. 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 Mask-2.0.0 KiCad files?
From the marcoster/mask repository on GitHub, at the commit this page was made from: the board is mask-ulp-nonsplit/mask-2.0.0.kicad_pcb and its schematic mask-0.0.0/keymatrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mask-2.0.0 design in my own project?
Its repository publishes it under the MPL-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).
