Questions
How big is the CH572 PCB?
It measures 17.8 × 28.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CH572 use?
23 parts, built around the CH572D. 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 CH572 KiCad files?
From the cyao1234/c57 repository on GitHub, at the commit this page was made from: the board is hardware/CH572.kicad_pcb and its schematic hardware/CH572.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CH572 design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
