Questions

How big is the Ch552t board panelized PCB?

It measures 100 × 98.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Ch552t board panelized use?

660 parts, built around the CH552T. 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 Ch552t board panelized KiCad files?

From the HongoMCC/ch552t_board repository on GitHub, at the commit this page was made from: the board is ch552t_board_panelized.kicad_pcb and its schematic ch552t_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Ch552t board panelized 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).
