Questions
How big is the Planck thk PCB?
It measures 228 × 114 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Planck thk use?
134 parts, built around the ATMEGA32A-PU. 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 Planck thk KiCad files?
From the olkb/planck_thk repository on GitHub, at the commit this page was made from: the board is planck-thk.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Planck thk 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).
