DRV8825 Stepper Motor Driver with Aluminum Heat Sink

The DRV8825 Stepper Motor Driver with Aluminum Heat Sink 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.

Description

  1. Microstep resolutions: full, 1/2, 1/4, 1/8, 1/16, and 1/32.
  2. Simple step and direction control interface
  3. Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
  4. Adjustable current control lets you set the maximum current output with a potentiometer. Hence lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
  5. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
  6. 45 V maximum supply voltage
  7. Built-in regulator (no external logic voltage supply needed)
  8. Can interface directly with 3.3 V and 5 V systems
  9. Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
  10. Short-to-ground and shorted-load protection
  11. 4-layer, 2 oz copper PCB for improved heat dissipation
  12. Exposed solderable ground pad below the driver IC on the bottom of the PCB
