Control Stepper Motor with A4988 Driver Module & Arduino

The A4988 stepper motor driver has an output drive capacity of up to 35V and ±2A. This allows you to control a bipolar stepper motor, such as the NEMA 17, at up to 2A output current per coil.

Furthermore, the output current is regulated, allowing for noiseless operation of the stepper motor and the elimination of resonance or ringing that is common in unregulated stepper driver designs.

The driver has a built-in translator for easy operation. This reduces the number of control pins to just two, one for controlling the steps and the other for controlling the spinning direction.

The driver offers five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step.

In order to ensure reliable operation, the driver has additional features such as under-voltage, shoot-through, short circuit, overcurrent, and thermal protection.
