Questions
How big is the Core PCB?
It measures 73 × 101.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Core use?
13 parts, built around the 74HCT245. 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 Core KiCad files?
From the dynamix/lolly repository on GitHub, at the commit this page was made from: the board is pcb/core/core.kicad_pcb and its schematic pcb/core/core.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Core design in my own project?
Its repository states no licence, so its author keeps all rights: ask dynamix before reusing the design.
