About Vipeco 2Pcs A4988 Stepper Motor Driver Module 3D

This product is a breakout board for Allegro 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 interfaceFive different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-stepAdjustable current control lets you set the maximum current output with a potentiometer,which lets you use voltages above your stepper motor rated voltage to achieve higher step ratesIntelligent 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 Color: GreenQuantity: 2 PcsWarning:Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver.
