Questions
How big is the Kb2 PCB?
It measures 235 × 72 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kb2 use?
61 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 Kb2 KiCad files?
From the LilleAila/projects repository on GitHub, at the commit this page was made from: the board is 2025/ergogen/kb2/pcbs/pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kb2 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
