It measures 99.1 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
27 parts, built around the NJM4558. 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 53175ddd/YM2203_DeveloperBoard repository on GitHub, at the commit this page was made from: the board is YM2203_DeveloperBoard.kicad_pcb and its schematic YM2203_DeveloperBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask 53175ddd before reusing the design.
