Questions

How big is the Schematic editor PCB?

It measures 67.5 × 74.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Schematic editor use?

30 parts, built around the SK6812MINI-E. 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 Schematic editor KiCad files?

From the necrymere/Necry-macropad repository on GitHub, at the commit this page was made from: the board is schematic editor.kicad_pcb and its schematic schematic editor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Schematic editor design in my own project?

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