It measures 93 × 60 mm and has 2 copper layers, 1.6 mm thick.
54 parts, built around the CP2102, ESP-WROOM-32D, AP2112K-3.3 and S8050. 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 ExploreEmbedded/hornbill-lights repository on GitHub, at the commit this page was made from: the board is Hardware/PCB/Hornbill Lights/Hornbill Lights.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 ExploreEmbedded before reusing the design.
