A4988 Stepper Driver Module for 3D Printer CNC Robotics 2 A Current Capacity Description

A4988 tepping Stepper Step Motor Driver Module 3D Printer Parts
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.
