WARNING

This project is a personal project, i just built one prototype. It's not considered complete, nor tested or error-free.

I won't develop this much, just releasing it as-is for anybody knowledgable picking up and maybe building upon it.

It is NOT ready to take the files and produce a working keyboard!

Questions

How big is the Chaotist PCB?

It measures 229.3 × 91.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Chaotist use?

105 parts. 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 Chaotist KiCad files?

From the Tschibo00/qmk repository on GitHub, at the commit this page was made from: the board is chaotist/pcb/chaotist.kicad_pcb and its schematic chaotist/pcb/chaotist.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Chaotist 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).
