Usually when I read through a build-out description like this, the author writes it for an audience that has a lot more background knowledge than I do. This article, on the other hand, was lucid and the explication helped me follow along.
I got to the part about 3.3V being derived from 5V and thought to myself "why not get it from 24V?" and then just a tiny bit later, there's the bit about USB and how Starfish can just take 5V from the USB host, and it clicked.
I also learned about Sparkfun's QWIIC connector in the aside about the chosen i2c bus switch having two "extra" channels. Love it, thanks for the article, Thea.
