The 84 most common of 103 parts.
It measures 85.1 × 53.3 mm and has 4 copper layers, 1.6 mm thick.
103 parts, built around the CH340C, ESP32-WROOM-32, AMS1117-3.3 and WS2812B. 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 low-poly-studio/esp32-faerfly repository on GitHub, at the commit this page was made from: the board is esp32-faerfly-V2.0/esp32-faerfly-V2.0.kicad_pcb and its schematic esp32-faerfly-V2.0/A_usb_interface.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 low-poly-studio before reusing the design.
