Questions
How big is the Tpkbd PCB?
It measures 43 × 38 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tpkbd use?
26 parts, built around the ATMEGA8515-16AU. 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 Tpkbd KiCad files?
From the ari-s/tpkbd repository on GitHub, at the commit this page was made from: the board is tpkbd.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tpkbd design in my own project?
Its repository states no licence, so its author keeps all rights: ask ari-s before reusing the design.
