Questions
How big is the ErgoDoxTW PCB?
It measures 200 × 200 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ErgoDoxTW use?
69 parts, built around the ATMEGA48A-AU. 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 ErgoDoxTW KiCad files?
From the semicontinuity/embedded repository on GitHub, at the commit this page was made from: the board is target/ergodoxal__main/case/rubber-pad-with-openings-right/ErgoDoxTW.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ErgoDoxTW design in my own project?
Its repository states no licence, so its author keeps all rights: ask semicontinuity before reusing the design.
