Questions
How big is the Batman PCB?
It measures 55.9 × 68.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Batman use?
16 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 Batman KiCad files?
From the Lor14N/Ghost-PCB-KeyChain repository on GitHub, at the commit this page was made from: the board is Batman.kicad_pcb and its schematic Batman.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Batman design in my own project?
Its repository states no licence, so its author keeps all rights: ask Lor14N before reusing the design.
