Questions
How big is the Kame32-pcb PCB?
It measures 67.6 × 30.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kame32-pcb use?
20 parts, built around the TEA 1-0505. 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 Kame32-pcb KiCad files?
From the JavierIH/kame32 repository on GitHub, at the commit this page was made from: the board is pcb/kame32-pcb/kame32-pcb.kicad_pcb and its schematic pcb/kame32-pcb/kame32-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kame32-pcb 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).
