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 – 5.5 V) and a motor supply voltage (8 – 35 )V. It can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).
This A4988 stepper driver is provided with heat sink to protect the board from overheating.
