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

Este es un gran kit que podría ser utilizado por cualquier persona que está buscando para construir su propia configuración CNC, o si su configuración actual necesita piezas de repuesto.

El conjunto está bastante bien, así como su relación calidad precio. Tanto Arduino como CNC Shield v3 y controladores funcionan perfectamente, llevo casi un mes con ellos y no he tenido ningún problema.

El pack incluye todo lo que indica en su descripción. Dejo unas fotos donde puede verse cómo llega el contenido y su aspecto.
