Feature(may vary by option.)

●A4988 driver board widely used in stepper motors /3D printer/CNC/engraving machines/Supported 3d printers.
●A4988 is a complete microstepping motor driver with built-in translator for easy operation.
●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.
●Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection.
