A4988 Bipolar Stepper Motor Driver Module

DC 35V 2A Microstep 32 Steps 3D Printer Robot Cnc Reprap Mks Gen Ramps Prusa Mendel Ultimaker

     Bipolar stepper motor driver module using the A4988 IC. It has adjustable current limiting, current and over-temperature protection. It works with DC 8V/35V motor supply voltage. It can deliver 1A x 2 load current. An aluminum heatsink comes with the product. An additional external heatsink is required at currents above 1A. With good cooling it can deliver 2A 2A, a total of 4A load current.

     It has 5 different step options. Full step, 1/2, 1/4, 1/8 and 1/16. With smart motor driving pwm functions, it reduces motor power consumption by adjusting the step count. It produces low motor noise.
