A4988 tepping Stepper Step Motor Driver Module 3D Printer Parts

1、Simple step and direction control interface, short-to-ground and shorted-load protection

2、Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step

3、Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)

4、Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection

5、Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor rated voltage to achieve higher step rates

Description:

A4988 is a complete micro-stepping motor driver with built-in translator

for easy operation. It includes a fixed off-time

current regulator, the regulator in slow or mixed decay modes. A4988

converter is the key to the easy implementation. As long as the "step"

input inputting one pulse drives the motor one micro-step. There are no

phase sequence tables, high frequency control lines, or complex

interfaces to program. A4988 interface is very suitable for complex

microprocessor is unavailable or is overburdened.

Features:

Simple step and direction control interface, short-to-ground and shorted-load protection.

Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step.

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.

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.

Internal synchronous

rectification control circuitry is provided to improve the pulse-width

modulation (PWM) operation power consumption.
