A4988 StepStick Stepper Driver+Heat sink For Reprap 3D Printer Parts Red Motor Driver With Heatsink Accessorie

• This product is a breakout board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection;
• This stepper motor driver lets you to operate bipolar stepper motors in full-, half-, quarter-, eighth-,
  and sixteenth-step modes, with an output drive capacity of up to 35 V and 2 A.
• The translator is the key to the easy implementation of the A4988.
• Simply inputting one pulse on the STEP input drives the motor one microstep.
• There are no phase sequence tables, high frequency control lines, or complex interfaces to program.
• The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.
• Features
• Simple step and direction control interface
• Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-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
• Intelligent chopping control that automatically selects the correct current decay mode
  (fast decay or slow decay)
• Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
• Short-to-ground and shorted-load protection
• Warning
• Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver.
• (More generally, rewiring anything while it is powered is asking for trouble.)
