Questions
How big is the Keyboard PCB?
It measures 200 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
225 parts, built around the ATTINY13A-SSU, WS2812B, PRTR5V0U2X and PSMN4R5-30YLC. 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 KiCad files?
From the dragonlock2/kicadboards repository on GitHub, at the commit this page was made from: the board is projects/keyboard/keyboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
