A4988 Reprap Stepper Motor Driver CNC 3D Printer

A4988 stepper motor driver is a complete microstepping motor driver with built-in translator for easy operation. The product can be full, half, 1/4, 1/8 and 1/16 step mode to operate bipolar stepper motor. According to a4988 datasheet, output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator can slow or mixed decay mode. The converter is the key to the easy implementation of the A4988. In inputting one pulse on the STEP input drives the motor one microstep. No phase sequence tables, high frequency control lines, or complex interfaces to programming. A4988 stepper motor driver interface is very suitable for complex microprocessor is unavailable or is overburdened. Shop 3d printer parts and 3d printer supplies from circuit.pk today!
