DESCRIPTION

DRV8825 micro-stepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and six micro-step resolutions (down to 1/32-step). It operates from 8.2 V to 45 V and can deliver 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). The driver has a pinout and interface that are nearly identical to those of A4988 stepper motor driver, so it can be used as a higher-performance drop-in replacement for those boards in many applications.

Micro-step settings:

 MODE0 MODE1 MODE2 Microstep Resolution
LOW LOW LOW FULL STEP
HIGH LOW LOW HALF STEP
LOW HIGH LOW 1/4 STEP
HIGH HIGH LOW 1/8 STEP
LOW LOW HIGH 1/16 STEP
HIGH LOW HIGH 1/32 STEP
LOW HIGH HIGH 1/32 STEP
HIGH HIGH HIGH 1/32 STEP


TECHNICAL DETAILS

  • Simple step and direction control interface
  • Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
  • Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
  • Configured for mixed decay mode
  • 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
  • 4-layer, 2 oz copper PCB for improved heat dissipation
  • Exposed solderable ground pad below the driver IC on the bottom of the PCB
  • Module size, pinout, and interface match those of A4988 stepper motor driver carriers in most respects
