Questions

How big is the Mosfet module PCB?

It measures 12 × 48 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Mosfet module use?

17 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.

Where can I download the Mosfet module KiCad files?

From the keyakko/mosfet-module repository on GitHub, at the commit this page was made from: the board is mosfet-module.kicad_pcb and its schematic mosfet-module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Mosfet module design in my own project?

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).
