Questions
How big is the Maghand PCB?
It measures 130.8 × 99.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Maghand use?
147 parts, built around the SK6812 and AO3401A. 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 Maghand KiCad files?
From the eteq/magkeyboard repository on GitHub, at the commit this page was made from: the board is maghand/maghand.kicad_pcb and its schematic maghand/keybank.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Maghand design in my own project?
Its repository states no licence, so its author keeps all rights: ask eteq before reusing the design.
