I'll cut right to the chase on the questions:
1.) Can a single DCC receiver run multiple motors at once?
2.) If a single receiver can, how many can it run? These motors would be separated from one another and not wired together.
3.) Is there a major difference in N scale receivers vs HO scale receivers?
I'm working on a project where I need to drive 4 independent motors. All the motors will be attached to the same two rails. I'm looking for recommendations on the what DCC receiver to use. I understand the basics of how DCC works but I don't know much beyond that. Are there low end and high end receivers with different levels of control and abilities?
