It measures 70 × 110 mm and has 2 copper layers, 1.6 mm thick.
143 parts, built around the MCP6004-E/P, LP5036RJV, MIC5205-3.3YM5 and PCM5102AQPWRQ1. 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 leechwort/morphtools-grape-pcb repository on GitHub, at the commit this page was made from: the board is grape/grape.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 leechwort before reusing the design.
