Questions
How big is the Rotunda base PCB?
It measures 24.7 × 25.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rotunda base use?
17 parts, built around the STM32F030F4P6. 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 Rotunda base KiCad files?
From the brainsmoke/rotunda repository on GitHub, at the commit this page was made from: the board is pcb/base/rotunda_base.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rotunda base design in my own project?
Its repository states no licence, so its author keeps all rights: ask brainsmoke before reusing the design.
