Questions
How big is the YAEWSBM2 PCB?
It measures 18.5 × 23.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the YAEWSBM2 use?
26 parts, built around the MMBT3904. 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 YAEWSBM2 KiCad files?
From the wormyrocks/YAEWSBM2-PCB repository on GitHub, at the commit this page was made from: the board is YAEWSBM2.kicad_pcb and its schematic YAEWSBM2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the YAEWSBM2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask wormyrocks before reusing the design.
