It measures 51.4 × 61 mm and has 2 copper layers, 1.6 mm thick.
38 parts, built around the FM25V10-G. 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 Emeryth/stm32gbcart repository on GitHub, at the commit this page was made from: the board is gbcart.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
