This module provides a direct interface between a stepper motor and a microcontroller. Ideal for Arduino and other development systems.
The driver is controlled with a 4-bit command and translated into the required pulses to drive a motor. The heart of the driver is a ULN2003AN IC. The module recommended an LED on each channel (total 4), which gives a good visual indication during stepping.
Voltage: 5 - 12 VDC
Maximum current per channel: 500 mA
