Using the motor shield and an Arduino Uno and trying to free up as many digital pins as possible. I see printed that pins D4,7,8,12 are reserved (indicated by a white dot) and I have a stepper motor connected to M3/M4 and not using any servos. Are there any of the reserved pins I can remove because I'm not using servos? Or are D4,7,8,12 reserved no matter what?
Appreciate any help.

Re: Motor Shield Pins
Thank you! So in my case I'll have 4,7,8,12 reserved as well as 5, 6 for the stepper. Thank you for directing me to the correct post.
