Hey looking for recommendations. Right now I am using a sabertooth 2x25 motor controller for my drive train, receiving signals from a raspberry pi. From what I am seeing online - there is a lot of mixed reviews regarding this sort of setup. Everything seems to be running fine on my end, but I am curious to see what is the best optimal way to interface and program a large DC motor. Reasons why I decided to use a pi was because I needed ROS to be set up with my robot to perform autonomous tasks.
I understand that the pi's clock is not powerful enough to give precise PWM output signals, while its running computations at the same time. Is there a board out there that could possibly handle both?
Edit: Around 6A continuous load for the motors, 12 V
