It measures 51.4 × 43.2 mm and has 2 copper layers, 1.6 mm thick.
17 parts, built around the LM1117-3.3. 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 brucemack/KC1FSZ-Control-Board-1 repository on GitHub, at the commit this page was made from: the board is KC1FSZ-Control-Board-1.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 brucemack before reusing the design.
