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

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).

El propio tablero es completamente compatible con el software y código Arduino. Esto significa que cualquier proyecto que encuentres diseñado para un tablero Arduino funcionará bien con éste. También significa que el código y los tutoriales están ampliamente disponibles para ayudarle a diseñar y programar su configuración CNC.
