Questions
How big is the Project for pcb PCB?
It measures 74.9 × 45.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Project for pcb use?
5 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 Project for pcb KiCad files?
From the Simonhajd/Macropad repository on GitHub, at the commit this page was made from: the board is pcb/project-for-pcb.kicad_pcb and its schematic pcb/project-for-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Project for pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Simonhajd before reusing the design.
