A4988 Stepper Motor Driver Carrier with Voltage Regulators

Pololu item #: 1183
Brand: Pololu
Status: Discontinued 

This product has been discontinued.

Please consider the A4988 carrier versions without integrated voltage regulators as alternatives.

This is a breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver. It has two voltage regulators (5 V and 3.3 V), eliminating the need for separate logic and motor supplies. The driver features adjustable current limiting, overcurrent and overtemperature protection, and five different microstep resolutions (down to 1/16-step). It operates from 8 – 35 V and 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 board ships with 0.1″ male header pins included but not soldered in.
