A4988 Stepper Motor Driver Features:

  1. Translator Excellence: Experience seamless motor operation with the built-in translator. Just input a pulse on the STEP input, and the motor takes a microstep – no fuss, no complex programming!
  2. Simple Interface: Straightforward step and direction control interface.
  3. Step Resolution Diversity: Choose from five step resolutions – full-step, half-step, quarter-step, eighth-step, and sixteenth-step.
  4. Tailored Current Control: Use the potentiometer to adjust the maximum current output. This feature allows you to use voltages higher than your stepper motor’s rated voltage for faster step rates.
  5. Universal Logic Supply: Compatible with both 3.3V and 5V logic supply.
  6. Intelligent Chopping: The driver smartly decides the apt current decay mode, be it fast decay or slow decay.
  7. Safety Features: Enjoy peace of mind with built-in over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection.

Customer Reviews (4.6 / 5 · 5 reviews)

Harper ★★★★★

Installing this driver on my CNC shield was straightforward, and the built-in translator made microstepping incredibly smooth right from the first test. The included heat sink keeps it cool even during long engraving runs.

Sophia V. ★★★★★

The heat sink was already attached when it arrived, which saved me a fiddly step. I just wired up the STEP and DIR pins, gave it a pulse, and the microstepping was smooth and silent right out of the box.

William ★★★★★

The built-in translator makes this driver stupidly simple to wire up—just feed it a pulse on STEP and it handles the microstepping math on its own. The included heat sink is a nice touch that keeps things cool even during longer prints. Already ordered a second batch for my next project.
