Questions
How big is the Keyboard tkl PCB?
It measures 360 × 130 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Keyboard tkl use?
128 parts, built around the AT32UC3B1512-Z1U, 74HC595 and LD1117S33CTR-HXY. 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 Keyboard tkl KiCad files?
From the ryanmaclean/kicad-stuff repository on GitHub, at the commit this page was made from: the board is keyboard-tkl.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard tkl 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).
