but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was possible to squeeze a DRV8837 DC motor driver and a pair of hall effect sensors on the first PCB ...

It’s a feature that allows the connected controller to know the exact position of the stepper motor, without the need ... steps due to mechanical or driver issues. Despite this, in general ...

Next, you will do a deep dive into stepper motor specs, operation, and commercial driver chips and packages. You will then do another lab exercise, this time on actuating a rotary sensor. We end the ...
