Questions
How big is the Plaid PCB?
It measures 228 × 98 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Plaid use?
139 parts, built around the ATMEGA328-PU. 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 Plaid KiCad files?
From the hsgw/plaid repository on GitHub, at the commit this page was made from: the board is pcb/plaid.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Plaid 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).
