Introduction to Core Chip A4988

A4988 is a DMOS micro step driver with converter and overcurrent protection. ltcan operate bipolar stepper motors in full, half, 14, 1/8,and 1/16 step modes,with output drive performance up to 55V and ± 2.A4988 includes a fixed turnoff time current regulator that can operate in siow or mixed decay modes. Theconverter is the key to the easy implementation of A4988.As long as a pulse isinput into the “stepper” input, the motor can be driven to generate microsteps.No need for phase sequence tables, high-frequency control lines, or complex in-terface programming. The A4988 interface is ‘very suitable for complex micro-processor unavailable or overloaded applications.

Differences from domestic A4988

1.The heat sink has been properly attached
2. R4=0 Q
3.The pins on both sides are black

CURRENT SETTING:Rs=0.1Q
Maximum current 2A

Suitable for

ln situations where stepper motors need to be driven;
it is a necessary module for building 3D printers,CNC, engraving machines.and other related components;
Supported 3D printers include Prusa MendeL, ultimaker,printbot,makerbot,and more.
You can refer to the Arduino code below to directly drive the motor.

Features of A4988

1. Suitable for driving stepper motors below 8V-~35V2A
2.There is only a simple stepper and directional control interface.
3.Five different stepper modes: full, half, 1/4,1/8,and 1/16
4.The adjustable potentiometer can adjust the maximum current output toachieve higher step rate.
5. Automatic current decay mode detection/selection.
6. Overheat shutdown circuit, undervoltage locking. cross current protection.
7. Ground short circuit protection and load short circuit protection.
