Ah thanks, that helps a lot.
How exactly do I change the pinout in firmware? It's not in the config.h
file. I'm planning on using the tmk firmware the README links to.

I'm doing a hand-wired Atreus build, and using a Pololu A-Star Micro

instructions it links to only provide wiring instructions for the
Teensy 2 microcontroller, not the A-Star Micro. Does anyone know what
pins on the A-Star Micro I should solder the rows and columns of a
hand-wired Atreus to?
Yeah, sure thing.
The simplest thing to do would be to follow the traces from the PCB:
You can see here that the rows are connected to PD2, PD3, PD1, and PD0:

The columns are PD7, PC6, PB5, PB4, and PE6 on the left, PD4 for the
middle, and PB7, PD6, PF7, PF6, and PB6 on the right (from the inside
out):

Of course, changing the pinout in the firmware if you get it mixed up is
very easy (especially compared to the task of hand-wiring the board) so
don't worry if you don't get it quite right.
I've attached a diagram labeling the pins just in case you don't have it.
Good luck.
