It measures 92 × 122 mm and has 2 copper layers, 1.6 mm thick.
115 parts, built around the RP2040, W25Q16JVSSIQ, DW01A and SRV05-4. 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 JeffreyWangDev/Sum-Intro-Number-thing repository on GitHub, at the commit this page was made from: the board is calc.kicad_pcb and its schematic calc.kicad_sch. 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).
