This might be a dumb question, but what is the difference between a motor driver and a motor controller? When I get on certain websites there are adds for both of them. I usually use continuous rotation servos but I am going to be making a robot that has to be a little faster so I thought I would check and see before I go and buy something I dont need.

generally, the "driver" would be the FET, the transistor that handles the current. Could be misused, though. Example/s?

Indeed, in a general sense, the motor controller would be something that would convert eg. a serial signal into a pwm signal, while a motor driver would be a "buffer" of some sort that is able to boost that signal into a higher current, higher voltage drive.

Both can be combined, and as such the names tend to get mixed up.

Lol, I was going to say that it says pretty much the difference. Controllers you can controll speed and have some feedback... :veryhappy:
