Questions
How big is the WemosMosfet PCB?
It measures 35.6 × 27 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WemosMosfet use?
26 parts, built around the WEMOS D1 MINI, BSS138, BSS84 and LL4148. 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 WemosMosfet KiCad files?
From the TheBlueManCoding/WemosMosfet repository on GitHub, at the commit this page was made from: the board is WemosMosfet.kicad_pcb and its schematic PNP_MOSFET.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WemosMosfet design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
