Questions
How big is the Limb44 PCB?
It measures 133.6 × 94.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Limb44 use?
70 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 Limb44 KiCad files?
From the yt3trees/Keyboards repository on GitHub, at the commit this page was made from: the board is Limb44/pcb/limb44.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Limb44 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).
