AS3158KT - Computer/Logic Controlled Bipolar Stepper Motor Driver, 5 - 50V, 6A

Ability Level 4: AdvancedProduct Formats Available: Pre-Assembled Module (AS) or
Self-Assembly Electronic Kit ( Soldering Required)

Driver for 4 wire (and 6 or 8 wire) bipolar stepper motors from 5 to 50Vdc using externally supplied 5V logic levels for controlling STEP and DIRECTION.

Inputs are opto-isolated making it ideal for CNC applications using a PC running suitable software (see User Manual below for details).

Can also be controlled using a microcontroller or simply two debounced switches connected to 5V.

  • Opto-isolated STEP and DIR inputs
  • Each 5V to 0V transition steps motor one position
  • Direction controlled by applying 0V or 5V to the input
  • Uses IRFZ44 and MTP2955 MOSFETs
  • Suitable for 5 - 50Vdc motors, up to 6 Amps
  • Separate power connections for driver and motor supply
  • Screw terminal blocks and solder pins for connections

Technical and operational details can be found in the documentation below.

DocumentationUser Manual

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
