Drive a 5-50V 4 wire (and 6 or 8 wire) bipolar stepper motors rated up to 6A using externally supplied 5V logic levels for controlling STEP and DIRECTION.
Control signal inputs are opto-isolated making it safe for CNC applications using a PC running suitable software (see User Manual below for details).
It can also be controlled using a microcontroller or simply two debounced switches connected to 5V.
Four pairs of MOSFETs are mounted back to back allowing you to add a heatsink of your choice if additional cooling is required.Features

PRE-ASSEMBLED Electronic Module (AS) Product Formats Info
A Visual Basic 6 program, VB_Stepper, is available for controlling stepper motor kits K113, K158 and K179 from a parallel port. All source has been provided to allow you to write your own visual basic programs. It uses the ActiveX component RSTimer which is a high speed timer from Ramon Sala. You can view his other components and software at http://www.elprogramari.com
