Product Technical Information
Technical Details
The A4988 StepStick Stepper Motor Driver Module is a compact motor control board designed for driving compatible bipolar stepper motors. It is widely used in projects that require controlled and accurate motor movement.
The module uses a simple STEP and DIR interface, allowing a microcontroller to control both the movement direction and the number of motor steps. Each pulse applied to the STEP input advances the motor according to the selected stepping mode, while the DIR input controls the rotation direction.
One of the key features of the A4988 driver is its microstepping capability. The module supports:
- Full Step
- Half Step
- 1/4 Step
- 1/8 Step
- 1/16 Step
Microstepping can help achieve smoother motor movement and improved positioning resolution in suitable applications.
The A4988 also provides adjustable current limiting, allowing the motor current to be configured appropriately. Proper current adjustment is important for reliable operation and for preventing excessive heating of the motor driver or connected motor.
