Questions

How big is the Cockpit PCB?

It measures 309.9 × 119.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Cockpit use?

144 parts, built around the 1N4148W, WS2812B, MSK12C02 and SS-12D00-G3. 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 Cockpit KiCad files?

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

Can I use the Cockpit 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).
