Intelligent cut-off control automatically selects the correct current reduction mode. (Fast reduction or slow reduction) EasyDriver - Stepper Motor Driver In stock ROB-12779 The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V or 0 to 3. Adjustable current control allows you to set the maximum current output with a potentiometer that allows you to use voltages above the rated voltage of the stepper motor to achieve high step rates. Five different step resolutions: full step, half step, quarter step, eighth step, and sixteenth step. An easy step and direction control interface. 
It is often useful to consider the driver as a ‘translator’ between input signals and the physical movement of the stepper motor.
This stepper motor driver allows you to control a bipolar stepper motor with up to 2A output current per coil. A stepper motor driver is an electronic component which can convert an input signal of some kind into movement of the stepper motor without itself being able to issue instructions (or control) the stepper motor. A4988 Stepper Motor Driver Circuit – Technical Specifications 0.1′ male headers are included but not soldered. Stepper Motor Driver 2-phase 4-wire Controller Speed Adjustable with Remote 621.99 Electronic World A++++++++. This module operates in the range of 8 V to 35V. and you can control motor up to about 1A per phase without heat sink or fan cooling. Rated at 2A per coil with adequate additional cooling. 
A4988 Stepper Motor Driver Circuit is a stepper motor driver module that contains Allegro’s A4988 micro step bipolar stepper motor driver, has adjustable current limiting, current and over-temperature protection, and five different micro step resolutions.
