From the project

USB-C PD trigger board (CH224A) — KiCad schematic and PCB layout, selectable 5/9/12/20/28V output

USB-C PD sink board using the CH224A to negotiate a fixed output voltage, selectable via DIP switch, with LED indication of the negotiated voltage.

Designed in KiCad while following Robert Feranec's video: https://www.youtube.com/watch?v=W0bmmF1wTEs

Schematic follows his walkthrough. Parts were sourced from LCSC and converted from EasyEDA to KiCad using easyeda2kicad, since I'm working in KiCad rather than EasyEDA. Layout and routing done independently.
