A4988 Stepper Motor Driver Module
Specification:
This stepper motor driver module is a breakout/carrier board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection and is Pololu / StepStick compatible. This stepper motor driver lets you control a bipolar stepper motor at 1 A continuous current per phase without a heatsink or cooling, and at up to 2 A maximum output current per coil if additional cooling is provided. An onboard potentiometer is used to adjust the current output.
Minimum operating voltage: 8V
Maximum operating voltage: 35V
Continuous current per phase: 1A
Maximum current per phase: 2A (with cooling)
Minimum logic voltage: 3V
Maximum logic voltage: 5.5V
Thermal shutdown circuitry
Ground fault protection
Load short-circuit protection
Microstep resolutions: Full, 1/2, 1/4, 1/8 and 1/16
