It measures 51.5 × 41.5 mm and has 2 copper layers, 1.6 mm thick.
33 parts, built around the AD8397AR and MCP4921-E/P. 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 visgence/dac_module repository on GitHub, at the commit this page was made from: the board is dac_module.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 visgence before reusing the design.
