Questions
How big is the Mss xcade PCB?
It measures 133.4 × 127 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mss xcade use?
233 parts, built around the ATTINY88-AU, ESP32-S2-SOLO-N8, AP63205WU and 74HC4049D. 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 Mss xcade KiCad files?
From the IowaScaledEngineering/mss-xcade repository on GitHub, at the commit this page was made from: the board is kicad/mss-xcade/mss-xcade.kicad_pcb and its schematic kicad/mss-xcade-can/mss-xcade-can.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mss xcade design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
