Questions
How big is the Glyph PCB?
It measures 85.3 × 35.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Glyph use?
50 parts, built around the ATMEGA1284P-MU. 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 Glyph KiCad files?
From the MalphasWats/Glyph repository on GitHub, at the commit this page was made from: the board is Glyph.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Glyph design in my own project?
Its repository states no licence, so its author keeps all rights: ask MalphasWats before reusing the design.
