A bot has 2 motors that keep popping the motor controllers but not the whole circuit. Is it any advantage to use ports 1 and 10 as opposed to the motor controller for these 2 motors
None, the PTC (fuse) is in the motor not the controller.
This isn’t entirely true… there is a PTC inside the Cortex also… actually two of them: one on ports 1-5 and the other on ports 6-10.
There is no advantage over using ports 1 & 10, but there is an advantage in balancing motors over the two different sides of the bank to balance the current load over these two PTCs.
Here’s a great post about it:
Ok, touché John. I thought Kevin was wanting to directly compare the power available for a motor on a pwm port with a motor on a 2 wire port.
