It measures 80 × 38 mm and has 4 copper layers, 1.6 mm thick.
99 parts, built around the MCP6002-I/P, PCM3060PW, EL357N(C)(TA)-G and AMS1117-3.3. 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 BarceP/CAT_Interface repository on GitHub, at the commit this page was made from: the board is Intercat.kicad_pcb and its schematic InterCAT_AnalogFilter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
