Description

  • Pololu 8-50V High-Power Stepper Motor Driver 36v4
  • Offers a wide operating voltage range of 8 to 50 V
  • Can deliver up to 4 A continuous per phase without extra cooling
  • Is highly configurable through SPI interface
  • Has optional STEP/DIR control pins
  • Provides optional STALL output enables stall detection when microstepping

The Pololu 8-50V 4A High-Power Stepper Motor Driver 36v4 combines the DRV8711 stepper motor driver IC from Texas Instruments with external MOSFETs to enable control of large bipolar stepper motors at operating voltages from 8 V to 50 V.

The DRV8711 has many configurable settings, so please see the DRV8711 datasheet (3 MB pdf) for a detailed explanation of its features and how to use them.

Powerful small driver

Got this to replace a larger TB6600 unit in a project spinning a desk lamp around. Has been working very well.
