It measures 59 × 53 mm and has 4 copper layers, 1.6 mm thick.
52 parts, built around the ESP32-S3, W25Q128JVSIQ, AMS1117-3.3 and USBLC6-2SC6. 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 nickzentmayer/HUB75-Matrix-Controller repository on GitHub, at the commit this page was made from: the board is HUB75_Matrix_Controller.kicad_pcb and its schematic HUB75_Matrix_Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask nickzentmayer before reusing the design.
