Questions
What parts does the CH572D Board use?
15 parts, built around the AMCA31-2R450G-S1F-T3 and TL3365AF180QG. 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 CH572D Board KiCad files?
From the LRNATHD/CH572D-Board repository on GitHub, at the commit this page was made from: the board is CH572D-Board/CH572D-Board.kicad_pcb and its schematic CH572D-Board/CH572D-Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CH572D Board design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
