Questions
What parts does the Mosfet switch use?
64 parts, built around the LM1117-3.3, IRFS4310ZPBF, BCX56 and ES1D. 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 switch KiCad files?
From the frawamudi/mosfet-switch repository on GitHub, at the commit this page was made from: the board is mosfet_switch.kicad_pcb and its schematic mosfet_switch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mosfet switch design in my own project?
Its repository states no licence, so its author keeps all rights: ask frawamudi before reusing the design.
