It measures 57.8 × 34 mm and has 2 copper layers, 1.6 mm thick.
65 parts, built around the ESP32-S3-WROOM-1-N16, ADXL375BCCZ-RL7, MIC5219-3.3YM5 and MIC5219-5.0YM5-TR. 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 gavin4d/dangerDonut repository on GitHub, at the commit this page was made from: the board is PCB/MainBoard/DangerDonut.kicad_pcb and its schematic PCB/Beacon/Beacon.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 gavin4d before reusing the design.
