Questions
What parts does the Balsamic use?
7 parts, built around the K210, ISP1807-LR-RS, CH552T and BMI160. 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 Balsamic KiCad files?
From the antoniog11/ring-project repository on GitHub, at the commit this page was made from: the board is hw/balsamic/balsamic.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Balsamic design in my own project?
Its repository states no licence, so its author keeps all rights: ask antoniog11 before reusing the design.
