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

• 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.

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 protectionWarning:➤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 ModuleOnly the above package content, other products are not included.SHIPPINGDomestic Buyers- We ship within 3 business days of payment, usually sooner- We offer FREE shipping on all orders!- We only ship to the lower 48 states, no APO/FPO addresses or PO Boxes allowed- We have confidence in our products, but if you are not fully satisfied please contact us within 30 days of purchase and you will get full refund.International buyers– please note: Import duties, taxes, and charges aren't included in the item price or postage cost.
