Questions
How big is the Ergodash PCB?
It measures 149.6 × 127.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ergodash use?
187 parts, built around the WS2812B and IRLML6344TRPBF. 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 Ergodash KiCad files?
From the omkbd/ErgoDash repository on GitHub, at the commit this page was made from: the board is PCB/Rev1.2/ergodash.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ergodash 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).
