Enhance Your Projects with the A4988 DMOS Microstepper Stepper Driver

Upgrade your stepper motor control with our high-performance Stepper Driver A4988, equipped with a heatsink and double-sided thermal adhesive tape. This breakout board unleashes the power of Allegro’s A4988 DMOS Microstepping Driver, complete with Translator and Overcurrent Protection. Prior to use, we recommend a thorough review of the A4988 datasheet to ensure optimal utilization of this product.

Key Features:

  • Smooth Motor Operation: Harness the versatility of bipolar stepper motors with adjustable step modes: full, half, quarter, eighth, and sixteenth steps. Achieve precise control over your motor’s movement.
  • User-Friendly Implementation: The A4988’s built-in translator eliminates the need for intricate programming. A single STEP input pulse corresponds to one microstep, simplifying your control interface.
  • Customizable Current Control: Tailor your motor’s performance using the adjustable current control. Set your desired maximum current output with a potentiometer, allowing for higher step rates by utilizing voltages beyond your stepper motor’s rated voltage.
  • Intelligent Chopping Control: Experience seamless transitions with intelligent chopping control, which intuitively selects the appropriate current decay mode (fast decay or slow decay).
  • Comprehensive Protection: Our A4988 driver is engineered with a suite of protective features, including over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection. You can trust in the durability of your stepper motor and driver.
  • Reliable Safeguards: With built-in short-to-ground and shorted-load protection, your equipment remains shielded from potential damage, enhancing the lifespan of your projects.
