Questions
How big is the Touchpad PCB?
It measures 41.3 × 30.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Touchpad use?
19 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 Touchpad KiCad files?
From the KOEGlike/meko repository on GitHub, at the commit this page was made from: the board is hardware/pcb_touchpad/touchpad.kicad_pcb and its schematic hardware/pcb/audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Touchpad 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).
