Questions

How big is the Calc PCB?

It measures 95.3 × 220.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Calc use?

93 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 Calc KiCad files?

From the flavian112/calc repository on GitHub, at the commit this page was made from: the board is hardware/calc/calc.kicad_pcb and its schematic hardware/calc/calc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Calc design in my own project?

Its repository states no licence, so its author keeps all rights: ask flavian112 before reusing the design.
