It measures 95.5 × 35 mm and has 2 copper layers, 1.6 mm thick.
11 parts, built around the PJ-320AS镀银环保. 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 palette-system/nubkey_module repository on GitHub, at the commit this page was made from: the board is hardware/nubkey_module_tester/nubkey_module_tester.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).
