Questions
How big is the Pacman PCB?
It measures 227.4 × 78 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pacman use?
150 parts, built around the RP2040, W25Q128JVSIQ and SK6812MINI-E. 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 Pacman KiCad files?
From the sendyyeah/pacman repository on GitHub, at the commit this page was made from: the board is pacman.kicad_pcb and its schematic pacman.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pacman 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).
