Stepper Motor Driver / Stepper Motor A4988 (Quantity Discount)

Description

1 unit - €3.30 5 units - €15.00 From now on, you can control bipolar stepper motors using the A4988 Stepper Motor Driver, requiring only two pins for control and enabling motor movement via "microstepping", a method used in applications demanding precise motor positioning. One of the major advantages of this module is its microstepping capability, configurable via pins MS1, MS2, and MS3. By setting these pins according to the sequence shown in the table below, you can select full-step, half-step, quarter-step (1/4), eighth-step (1/8), or sixteenth-step (1/16) modes. This module is controlled by the A4988 chip (datasheet) and operates with supply voltages between 3 V and 5.5 V. For the motor, it supports external power supply from 8 V to 35 V. A potentiometer on the board allows adjustment of the output current. Basic stepper motor control is achieved using two microcontroller pins connected to the module's STEP (step) and DIR (direction) pins. Includes: • 1× A4988 Stepper Motor Driver; • 1× Heat Sink.
