It measures 49.2 × 65.2 mm and has 2 copper layers, 1.6 mm thick.
49 parts, built around the PT2399. 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 GadgetReboot/PT2399_Breakout repository on GitHub, at the commit this page was made from: the board is KiCad/GR_PT2399_Breakout.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 GadgetReboot before reusing the design.
