Questions
What parts does the Ghostmesh macropad use?
13 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 Ghostmesh macropad KiCad files?
From the GTXPOFFIC-developer/ghostmesh-macropad repository on GitHub, at the commit this page was made from: the board is PCB/Ghostmesh Macropad.kicad_pcb and its schematic PCB/Ghostmesh Macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ghostmesh macropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask GTXPOFFIC-developer before reusing the design.
