Questions
How big is the Plotter PCB?
It measures 77 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Plotter use?
30 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 Plotter KiCad files?
From the MD12c/Plotter-PCB repository on GitHub, at the commit this page was made from: the board is Plotter/Plotter.kicad_pcb and its schematic Plotter/Plotter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Plotter design in my own project?
Its repository states no licence, so its author keeps all rights: ask MD12c before reusing the design.
