Questions
How big is the Development board ch552 PCB?
It measures 32.5 × 15.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Development board ch552 use?
10 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 Development board ch552 KiCad files?
From the ricelectric/development-board-ch552 repository on GitHub, at the commit this page was made from: the board is kicad/development_board_ch552.kicad_pcb and its schematic kicad/development_board_ch552.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Development board ch552 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).
