Description

Stepper motor driver Allegro’s A4988 DMOS Micro-stepping Driver with adjustable current limiting, overcurrent and overtemperature protection, and five different microstep resolutions (down to 1/16-step).

The driver requires a logic supply voltage (3 – 5.5V) and a motor supply voltage (8 – 35 )V. It can deliver up to approximately 1A per phase without a heat sink or forced air flow (it is rated for 2A per coil with sufficient additional cooling).

This A4988 stepper driver is provided with heat sink to protect the board from overheating.
