Features Of Drv8825 Stepper Motor Driver RAMPS Heat Sink 3D Printer Motor Driver:

• Microstep resolutions:?full, 1/2, 1/4, 1/8, 1/16, and 1/32.
• 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. Hence lets you use voltages above your stepper motor?s rated voltage to achieve higher step rates
• 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
• 4-layer, 2?oz copper PCB for improved heat dissipation
• Exposed solderable ground pad below the driver IC on the bottom of the PCB
