A4988 Stepper Motor Driver With Control Board

The A4988 stepper motor driver carrier is a breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver.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). As well
as the A4988, this listing also includes a very handy shield for the stepper driver. The shield includes female headers for power, male headers for stepper
motor control, a DIP switch for step resolution, 4 pin housing for connection to the stepper motor, and an on-board capacitor. Please see below for a
description of the breakout board.
