It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
28 parts, built around the 2SK4017(Q) and VL53L0X. 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 CALIL/openbookcamera repository on GitHub, at the commit this page was made from: the board is controller/circuit/shoei.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
