![]() ![]() The resolution (step size) selector pins (MS1, MS2, and MS3) allow you to select one of the five step resolutions according to the table below. ![]() A4988 Specifications Minimum operating voltageįor more information you can check out the datasheet here. You can find more specifications in the table below. The A4988 driver chip has several safety functions built-in like overcurrent, short circuit, under-voltage lockout, and over-temperature protection. TB6600 Stepper Motor Driver with Arduino Tutorial.This driver can be used with the same code as the A4988 and has a current rating of 3.5 A. ![]() If you need to control larger stepper motors like NEMA 23, take a look at the TB6600 stepper motor driver. The driver has a maximum output capacity of 35 V and ± 2 A which is great for driving small to medium-sized stepper motors like a NEMA 17 bipolar stepper motor. This integrated motor driver makes interfacing with a microcontroller super easy as you only need two pins to control both the speed and the direction of the stepper motor. About the driverĪt the heart of the A4988 driver you will find a chip made by Allegro MicroSystems: the A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection.

It makes wiring much easier and is a great option if you need a more permanent solution than a breadboard. Such a shield already includes capacitors and offers an easy way to select the microstepping resolution. I like to use this driver in combination with a CNC-shield or expansion board.
