It measures 68.3 × 31.8 mm and has 2 copper layers, 1.6 mm thick.
34 parts, built around the ATMEGA32U4-MU, WS2812B and PRTR5V0U2X. 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 beekeeb/AprilMacro3 repository on GitHub, at the commit this page was made from: the board is pcb/april.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 beekeeb before reusing the design.
