Questions
How big is the Sbc hat PCB?
It measures 85 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sbc hat use?
94 parts, built around the MAX3232IPWRE4 and SC16IS752IPW. 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 Sbc hat KiCad files?
From the GSO-soslab/alpha_hardware_release repository on GitHub, at the commit this page was made from: the board is Electronics/sbc_hat/sbc_hat.kicad_pcb and its schematic Electronics/RISE_battery_power_distribution2/RISE_battery_power_distribution.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sbc hat design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
