Microstep Selection Pins: The A4988 driver has three-step resolution selector inputs, i.e., MS1, MS2 & MS3. VDD is employed for driving the interior logic circuitry which may be 3V to 5V whereas VMOT supplies power for the motor which may be 8V to 35 V.Ģ. Power Supply Pins: The pin include VDD & VMOT & Pair of GND pins. The A4988 driver has total of 16 pins which are as follows:ġ. Short-to-ground and shorted-load protection.

Microstep resolution: Full step, ½ step, ¼ step, 1/8 and 1/16 step.It is rated for 2 A per coil with sufficient additional cooling. It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced airflow. The breakout board from Allegro features adjustable current limiting, over-current and over-temperature protection and five different microstep resolutions. The A4988 is a complete Microstepping Motor Driver with a built-in translator for easy operation. S.N.Īrduino UNO R3/ Nano or Any other Arduino Board The component purchase link is given as well. All the components can be easily purchased from Amazon. The following are the components required for learning this tutorial. Therefore we need Stepper Driver Module like A4988 or DRV8825. But the NEMA17 Stepper Motor is requires 8V-35V Power as the torque is too high. The 28BYJ-48 is a 5-wire unipolar stepper motor that runs on 5 volts and doesn’t require any driver. In the previous tutorial we learned Controlling the Stepper Motor with Potentiometer and also with Joystick. The DIR pin will control the rotation direction and the STEP pin will control the steps.
Thus, we can control the stepper motor with just 2 pins from our controller. The A4988 is a micro-stepping driver for controlling bipolar stepper motors which have a built-in translator for easy operation. In this tutorial we will Control the NEMA17 Stepper Motor with A4988 Driver Module & Arduino. Overview: Control Stepper Motor with A4988 Driver & Arduino 11 Control NEMA17 Stepper Motor with A4988 & Potentiometer.
