5Pcs A4988 StepStick Stepper Motor Driver Module + Heat Sink for 3D Printer RepRap

Description

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.) Package Include: 5x A4988 Stepper Motor Driver Module Only the above package content, other products are not included.

Features

• 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.
• 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.
• 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.
• 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.
