With a simple interface and multiple step resolutions, it ensures precise motor control while incorporating essential safety features. ## Description This stepper motor driver module is a breakout/carrier board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection and is Pololu / StepStick compatible. This stepper motor driver lets you control a bipolar stepper motor at 1 A continuous current per phase without a heatsink or cooling, and at up to 2 A maximum output current per coil if additional cooling is provided. An onboard potentiometer is used to adjust the current output.This driver can control the stepper motor with just 2 pins from the controller, one for controlling the rotation direction and the other for controlling the steps. Stepper motors typically have a step size specification (e.g. 1.8° or 200 steps per revolution), which applies to full steps. This microstepping driver allows higher resolutions by providing intermediate step locations, which are achieved by energizing the coils with intermediate current levels. For instance, driving a motor in quarter-step mode will give the 200-step-per-revolution motor 800 microsteps per revolution by using four different current levels. This driver module provides five different step resolutions: Full-step, 1/2, 1/4, 1/8 and 1/16 step.Ideal for applications that do not have a complex microprocessor available, and pairs well with Arduino microcontrollers.Specifications:Minimum operating voltage: 8VMaximum operating voltage: 35VContinuous current per phase: 1AMaximum current per phase: 2A (with cooling)Minimum logic voltage: 3VMaximum logic voltage: 5.5VThermal shutdown circuitry, Ground fault protection, Load short-circuit protectionMicrostep resolutions: Full, 1/2, 1/4, 1/8 and 1/16Package contents:2 x A4988 Stepper motor driver module2 x HeatsinkPrinted Operation and Programming Instructions Review: It works - Works and got me through my senior design project Review: Works really well with NEMA17 stepper. - If you are needing to drive a NEMA 17 motor up to 1 or maybe 2 Amps this driver module may be just what you need. I have seen a lot of reviews that mention module overheating and motors that just vibrate or run erratically when connected to the module and I have to say the same thing happened to me. It wasn’t the driver module’s fault though. I found that if you crank the reference voltage potentiometer fully counterclockwise before ever connecting power and then easing it up clockwise incrementally once power is applied and monitoring the stepper motor coil amperage you will avoid the overheating issue. The buzzing motor, or erratic operation issue occurs if you don’t connect the motor windings up to the driver outputs 1A, 1B, 2A, and 2B correctly. StepperOnline labels the windings as A+, A-, B+, and B-. If you connect A+ to 1A, A- to 1B, B+ to 2A, and B- to 2B things work as you would expect. Once I figured this out I was able to drive the motor to 0.6A under full load (stalled motor armature) for several minutes with no signs of overheating in the driver module or the stepper motor. My power supply could only drive 12 volts at 0.6A so I couldn’t push things any higher but since things stayed cool and stable at those levels (except for my power supply!) I am pretty confident that when my new power supply comes in I will still be OK at 1.5 to 2 amps. Will come back and edit this review if I find out otherwise. At this point though, I am very satisfied with the A4988 stepper motor driver! One other note - one of the two tantalum capacitors I had in parallel across the motor supply power connectors in the photo exploded like a firecracker during this testing. And, no, I didn’t have the polarity wrong on the one that exploded. They were both rated at 33uF and 35 volts. Switched to a 2200uF 50v electrolytic and it help up just fine. Guessing that transients generated by the motor windings exceeded the voltage rating and caused the poor little bugger to short out and over heat. ## Features - Control a bipolar stepper motor at up to 2 A current per phase. An onboard potentiometer is used to adjust the current output - Simple step and direction control interface with five step resolutions: full-step, half-step, 1/4-step, 1/8-step, and 1/16-step - Uses just 2 pins from the microcontroller, one for controlling the rotation direction and the other for controlling the steps - 8V to 35V output voltage range at up to 2A current - Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QT7N3T2 | | Best Sellers Rank | #408,589 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #85 in 3D Printer Interface & Driver Modules | | Brand | Envistia | | Brand Name | Envistia | | Color | Red | | Customer Reviews | 4.3 out of 5 stars 20 Reviews | | Display Type | LCD | | Manufacturer | Envistia Mall | | Material | Metal | | Material Type | Metal | | UPC | 732387204992 | ## Images ![A4988 Stepper Motor Driver Module for Pololu RepRap 3D Printer StepStick (Pack of 2) - Image 1](https://m.media-amazon.com/images/I/611ojhEW7wL.jpg) ![A4988 Stepper Motor Driver Module for Pololu RepRap 3D Printer StepStick (Pack of 2) - Image 2](https://m.media-amazon.com/images/I/61RvxhMrrjL.jpg) ![A4988 Stepper Motor Driver Module for Pololu RepRap 3D Printer StepStick (Pack of 2) - Image 3](https://m.media-amazon.com/images/I/51oUrEiOQGL.jpg) ![A4988 Stepper Motor Driver Module for Pololu RepRap 3D Printer StepStick (Pack of 2) - Image 4](https://m.media-amazon.com/images/I/51xqv4UYGeL.jpg) ![A4988 Stepper Motor Driver Module for Pololu RepRap 3D Printer StepStick (Pack of 2) - Image 5](https://m.media-amazon.com/images/I/51OdNh0oV9L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works *by P***. on August 19, 2025* Works and got me through my senior design project ### ⭐⭐⭐⭐⭐ Works really well with NEMA17 stepper. *by O***6 on January 20, 2025* If you are needing to drive a NEMA 17 motor up to 1 or maybe 2 Amps this driver module may be just what you need.

The filament was not advancing. I replaced the stepper driver with this one, and it started working. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/123935750-a4988-stepper-motor-driver-module-for-pololu-reprap-3d-printer](https://www.desertcart.at/products/123935750-a4988-stepper-motor-driver-module-for-pololu-reprap-3d-printer) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-06-05*
