Questions

How big is the Ch32v203-dev PCB?

It measures 27.7 × 59.7 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Ch32v203-dev use?

36 parts, built around the CH32V203C8U6, DMG2305UX-7, KH-TYPE-C-16P and SD101CWS. 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 Ch32v203-dev KiCad files?

From the Ismael034/ch32v203-dev repository on GitHub, at the commit this page was made from: the board is ch32v203_dev.kicad_pcb and its schematic 1_1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Ch32v203-dev design in my own project?

Its repository states no licence, so its author keeps all rights: ask Ismael034 before reusing the design.
