It measures 56.5 × 65 mm and has 2 copper layers, 1.6 mm thick.
31 parts, built around the BSS138. 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 hansliss/pi1541 repository on GitHub, at the commit this page was made from: the board is Pi1541.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
