Questions

How big is the Karno65 PCB?

It measures 101.6 × 44.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Karno65 use?

156 parts, built around the ATMEGA328-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 Karno65 KiCad files?

From the chenull/karno65 repository on GitHub, at the commit this page was made from: the board is karno65.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Karno65 design in my own project?

Its repository states no licence, so its author keeps all rights: ask chenull before reusing the design.
