Description

Breakout board for Allegro's A4988 microstepping bipolar stepper motor driver
Simple step and direction control interface
Operates from 8-35 V and delivers up to 2A per coil
Adjustable current limiting and five different microstep resolutions

The Pololu 8-35V 2A Single Bipolar Stepper Motor Driver A4988  is a breakout board for Allegro's easy-to-use A4988 microstepping bipolar stepper motor driver and is a drop-in replacement for the A4983 stepper motor driver carrier. The driver features adjustable current limiting, overcurrent protection, and five different microstep resolutions.

Pololu 8-35V 2A Single Bipolar Stepper Motor Driver A4988 - Click to Enlarge

This breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and five different microstep resolutions (down to 1/16-step). It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling). This board ships with 0.1″ male header pins included but not soldered in.


Features:
Simple step and direction control interface
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
Short to ground and shorted-load protection

Specifications

  • Minimum operating voltage: 8 V
  • Maximum operating voltage: 35 V

NICE DRIVER

Review by James
General

This is a really nice stepper driver, with good instructions so you can easily use the micro-stepping modes, current limiting, etc., to get the max performance out of your motor. Even if you don't want to use the features, just leave the mode pins unconnected and you have a simple 2-wire interface to run the 4-wire motor. You can't beat this device for the money. Does get hot if you leave the enable pin on.

Tiny and nice

Review by Richard
General

Needed to add heat sinks at the bottom of the pcb where the thermal vias are and a copper heat sink on the top of the chip; the way I've used it temps got >>80 degrees C; now it works fine. Sometimes my steppers are showing strange things (stepping back instead of forward); probably a temp thing because it only happens after driving them for a while. For "lights" stuff this is more than ok!

Much smaller than I thought it would be

Review by Charles
General

My mistake I did not look closely at the size and had thought it would have a much larger foot print.

I have yet to use the item but can see no reason that it will not work as it is week designed and assembled.

Certainly worth a punt at the prince

Great Value at good price

Review by ALBERT
General

It's a very user friendly Driver. It's easy to star up and well featured PCB

Easy to use

Review by Alvin
General

Pretty much plug and play by following the pin layouts on the datasheet. Only requires step and direction inputs to run. Works with bipolar and unipolar stepper motors. More info can be found on the pololu page.

Petit mais très bon

Review by Jocelyn

Très bon produit fonctionne très bien avec linux cnc et tous les moteurs bipolaire et hybride

Product is easy to break

Review by Richard
General

It was my fault but I broke two of these. They also wouldn't drive my hybrid stepper. Instead, I would recommend the higher performance stepper driver from pololu with the TI chip.

Tiny but wonderful

Review by Allan
General

Boy is it ever tiny. But it came with pins and was laid out so my stepper motor plugged into it without fuss. And yes, it does the job nicely.

Great Basic Module

Review by Jeffrey
General

Works great for someone needing a basic module that uses Step+Direction input.
