Fisheiyy/Better-Klipper-Expander
A RP2040 based 3D Printer Port Expander
It measures 179.3 × 72.5 mm and has 4 copper layers, 1.6 mm thick.
59 parts, built around the TSOP31438, ULN2003BD, ICM-42670-P and S1A. 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 alicedimauro/Tilt repository on GitHub, at the commit this page was made from: the board is Starter/Starter.kicad_pcb and its schematic Starter/Starter.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 alicedimauro before reusing the design.
