Frequently Asked Questions
Microstepping is set using the MS1, MS2, and MS3 pins on the module according to the desired step resolution.
No, each A4988 module controls only one stepper motor. Multiple modules are needed for multiple motors.
The A4988 works with most bipolar stepper motors within the voltage and current ratings of the driver.
For currents above 1A per phase or continuous operation, it is recommended to use a heat sink for better thermal management.
