Questions
How big is the OrthoProject75 PCB?
It measures 285 × 94 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OrthoProject75 use?
150 parts, built around the USBLC6-2SC6 and XC6206P332MR. 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 OrthoProject75 KiCad files?
From the Wa1tee/OrthoKeyboard75 repository on GitHub, at the commit this page was made from: the board is orthoProject75.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OrthoProject75 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).
