Questions
How big is the USBPD12VModule PCB?
It measures 25 × 34.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USBPD12VModule use?
20 parts, built around the CH224K, FDS4935A, RK73H2ATTD1002F and RK73H2ATTD1001F. 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 USBPD12VModule KiCad files?
From the wakimizufu/TBSEQ repository on GitHub, at the commit this page was made from: the board is USBPD12VModule/USBPD12VModule.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the USBPD12VModule design in my own project?
Its repository states no licence, so its author keeps all rights: ask wakimizufu before reusing the design.
