This is a reversible 100mm x 100mm pcb with support for mx or choc switches (no hotswap), per key led, rotary encoders, and exposes the SDA/SCL/GND/VCC lines in the form of the pimoroni trackball pins (meaning you can…

It measures 266.7 × 95.3 mm and has 2 copper layers, 1.6 mm thick.
87 parts, built around the 1N4148W. 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 tamaroh/maggie42 repository on GitHub, at the commit this page was made from: the board is kicad/pcb.kicad_pcb and its schematic kicad/bottom_plate/bottom_plate.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 tamaroh before reusing the design.
