It measures 52 × 28 mm and has 2 copper layers, 1.6 mm thick.
20 parts, built around the 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 knightfox75/Atari_2600_AV_Mod repository on GitHub, at the commit this page was made from: the board is KiCad Project/atari_2600_av_mod.kicad_pcb and its schematic KiCad Project/atari_2600_av_mod.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
