Questions
How big is the Gravestone PCB?
It measures 60 × 46.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gravestone use?
30 parts, built around the ATMEGA32U2-AU and PRTR5V0U2X. 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 Gravestone KiCad files?
From the Prkns/Gravestone repository on GitHub, at the commit this page was made from: the board is PCB/Gravestone.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gravestone design in my own project?
Its repository states no licence, so its author keeps all rights: ask Prkns before reusing the design.
