What are the gotchas to porting Kaleidoscope to different keyboards?

This has been discussed a bit already, but not in great depth:

Hardware differences between the Model01 and OLKB boards

The main difference is that Planck, Preonic, Atomic, and the rest of the boards from OLKB are based on the Teensy, which is a small USB development board built around the Atmega32u4 processor. The Model01 is built around the same Atmega32u4 processor, but in a slightly different way. To put it another way, they have the same brains, but slightly different bodies. The Teensy is USB Mini-B, the Model01 is USB-C, and there are other subtle differences in how the body was built around it. The pin …

So, the Model 01 is built around an ATMega32u4 in each half of the keyboard.

Actually, if my memory is correct, it’s one ATmega32u4 (in the left half), and two ATtiny88’s (one in each half, doing the key scanning).
