Questions
How big is the Ghostchess brains v1 PCB?
It measures 150 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ghostchess brains v1 use?
15 parts, built around the ATMEGA644PA-PU. 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 Ghostchess brains v1 KiCad files?
From the iley/ghostchess repository on GitHub, at the commit this page was made from: the board is pcb/ghostchess_brains_v1/ghostchess_brains_v1.kicad_pcb and its schematic pcb/ghostchess_brains_v1/ghostchess_brains_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ghostchess brains v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask iley before reusing the design.
