Questions

How big is the Sweet16 PCB?

It measures 140 × 60 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Sweet16 use?

113 parts, built around the LM358. 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 Sweet16 KiCad files?

From the davedarko/Zynthia16 repository on GitHub, at the commit this page was made from: the board is Sweet16 Rev 1/Sweet16.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Sweet16 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).
