The 65 most common of 69 parts.
It measures 77.7 × 75.9 mm and has 2 copper layers, 1.6 mm thick.
69 parts, built around the BMP388 and ICM20948. 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.
From the dgramop/v2SLI repository on GitHub, at the commit this page was made from: the board is v2SLI.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask dgramop before reusing the design.
