Questions
How big is the Yacc46 plate PCB?
It measures 285.5 × 112.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Yacc46 plate use?
144 parts, built around the ATMEGA32U4-AU, WS2812B and PRTR5V0U2X. 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 Yacc46 plate KiCad files?
From the 1m38/keyboards repository on GitHub, at the commit this page was made from: the board is yacc46/plate_v0.3/yacc46_plate.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Yacc46 plate 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).
