Adafruit A4988 Stepper Driver Breakout (6109)
Overview
A compact Adafruit breakout board built around the Allegro A4988 stepper motor driver IC. It provides the standard step/dir control inputs plus pins for enable/sleep and current-limit adjustment, packaged for breadboard and prototyping use. The board is intended to simplify driving bipolar stepper motors from microcontrollers and development boards.
Why Choose This Part
This breakout exposes the common STEP/DIR interface and control pins in a small, breadboard-friendly form factor for rapid prototyping. It includes an adjustable current-limit control and standard protection features provided by the A4988 driver IC, simplifying motor setup and protecting against common fault conditions. The board is low-cost, widely supported, and easy to integrate with hobby and development microcontrollers.
Applications
Getting Started
Hook up a suitable motor power supply, connect STEP and DIR from your microcontroller, and wire the motor coils to the board. Before running, adjust the on-board current-limit potentiometer and use a heatsink or cooling as needed; consult Adafruit's product page and tutorial for wiring diagrams and recommended precautions. Typical hosts include Arduino-compatible boards and other microcontrollers that can generate step pulses and direction signals.
