Scanning quickly down the page to the first schematics as I did, I thought "but this thing's tiny? and so arbitraily-sized!", so scrolled back up a wee bit.

Ah, of course. Inches.

Stuff this scale should be drawn in millimetres, imho. Keep inches for tables and chairs.

It's meant to be breadboard-compatible, and breadboard pin sockets are normally spaced at 0.1 inch.

You can see in the first schematic that it's 0.9" by 2.0", which gives you 9x20 hole positions.
