A4988 stepper driver
Each piece in a sealed static-free bag
Small piece heat sink for the chip is included.
The A4988 is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Over current Protection; we therefore recommend careful reading of the A4988 datasheet (380k pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.
