Questions
How big is the Core PCB?
It measures 63.5 × 63.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Core use?
91 parts, built around the BMP388, BNO055, MAX17049G+ and USBLC6-2SC6. 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 calstar/cas-core-hw repository on GitHub, at the commit this page was made from: the board is core/core.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Core design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
