Questions

How big is the Etch a sketch PCB?

It measures 100 × 62 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Etch a sketch use?

38 parts, built around the STM32F401RET6, AMS1117-3.3 and B5819W. 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 Etch a sketch KiCad files?

From the disposedtrolley/etch-a-sketch repository on GitHub, at the commit this page was made from: the board is Hardware/etch-a-sketch/etch-a-sketch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Etch a sketch design in my own project?

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