A4988 Stepper Motor Driver:

A4988 Stepper Motor Driver Board is a breakout board for Allegro’s A4988 DMOS Micro stepping Driver with Translator and Overcurrent Protection; please read the A4988 datasheet carefully before using this product.

Low RDS (On) Output

Automatic current decay mode detection / selection

Mix with slow current decay modes

Synchronous rectification for low power dissipation

Internal UVLO

Crossover-current protection

3.3 and 5 V compatible logic supply

Thermal shutdown circuitry

Ground fault protection

Load short-circuit protection

Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16

Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (More generally, rewiring anything while it is powered is asking for trouble).

Package includes:

1x CNC Shield Board

1x Arduino UNO R3 Board

4x A4988 Stepper Motor Driver
