Questions
How big is the AND PCB?
It measures 25 × 20.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AND use?
11 parts, built around the BSS138. 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 AND KiCad files?
From the jojo20000-basic/Logic-for-Beginners repository on GitHub, at the commit this page was made from: the board is V2/AND,OR,NOT/NOT/AND.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AND design in my own project?
Its repository states no licence, so its author keeps all rights: ask jojo20000-basic before reusing the design.
