Re-purposing a motherboard MOSFET to serve as an electrical switch.
Panel is an open-source printed circuit board by keyakko, from the keyakko/mosfet-module repository on GitHub, published under the MIT licence. It is a 2-layer board of 96 × 98 mm with 1,020 parts on 84 nets, routed with 324 tracks and 192 vias.
It is built around the CSD17578Q5A. Its parts include 36 resistors, 36 connectors, 24 transistors and 12 diodes.

I am a beginner in circuit design, so there may be issues with the wiring.

The 192 most common of 1,020 parts.
It measures 96 × 98 mm and has 2 copper layers, 1.6 mm thick.
1,020 parts, built around the CSD17578Q5A. 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 keyakko/mosfet-module repository on GitHub, at the commit this page was made from: the board is panel.kicad_pcb and its schematic mosfet-module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
