Questions

How big is the V2SLI PCB?

It measures 77.7 × 75.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the V2SLI use?

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.

Where can I download the V2SLI KiCad files?

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.

Can I use the V2SLI design in my own project?

Its repository states no licence, so its author keeps all rights: ask dgramop before reusing the design.
