DRV8825 Stepper Motor Driver with Aluminum Heat Sink

Sepcifications

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
