Geeetech StepStick A4988 Stepper Driver,Sanguinololu RAMPS Pololu Prusa Mendel

Description
 
 
This product is a breakout board for Allegro¡¯s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; please read the A4988 datasheet carefully before using this product. 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
