The DRV8825 Stepper Motor Driver Module is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of the A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications. The DRV8825 features adjustable current limiting, overcurrent, and over-temperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and delivers up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).

Specifications

  • Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
  • Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
  • 45 V maximum supply voltage
  • Built-in regulator (no external logic voltage supply needed)
  • Can interface directly with 3.3 V and 5 V systems
  • Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
  • Short-to-ground and shorted-load protection
