It measures 50 × 100 mm and has 2 copper layers, 1.6 mm thick.
44 parts, built around the TA7291SG and 2SC1815. 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 soburi/mft2014 repository on GitHub, at the commit this page was made from: the board is kicad/mft2014.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 soburi before reusing the design.
