Questions

How big is the Smart chessboard controller PCB?

It measures 89.8 × 92.5 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Smart chessboard controller use?

75 parts, built around the CP2102-GMR, PCA9548APW, SP0503BAHTG and TXS0102DCT. 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 Smart chessboard controller KiCad files?

From the shuki25/smart-chessboard-controller repository on GitHub, at the commit this page was made from: the board is smart-chessboard-controller.kicad_pcb and its schematic smart-chessboard-controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Smart chessboard controller design in my own project?

Its repository states no licence, so its author keeps all rights: ask shuki25 before reusing the design.
