HobbyCNC EZ Driver Board Kit

Control 3 Stepper Motors From Your Computers Printer Port! Ideal For Desktop Machining and Robots! Control Routers, Lathes, Mills, PCB Drillers, and Engravers! Just About Anything!

What’s makes the EZ Driver Board Kit different than others?:

  • EZ to assemble as part count is very low. Lessens chance of assembly errors.
  • 36VDC maximum input gives a very wide margin to help prevent damage with voltage surges.
  • Smaller footprint for EZ installations.


  • RoHS Compliant
  • 3 Axis Unipolar Chopper control.
  • Individual OR simultaneous control of 2/4 Phase Stepper Motors.
  • Accepts 5, 6, or 8 wire stepper motors only. 4 wire types are not usable.
  • 36VDC maximum input voltage, 12VDC minimum input voltage. 24VDC Minimum Recommended Voltage.
  • 3.0 Amps Maximum per Phase, 500ma (.5A) minimum. Each axis adjustable throughout this range.
  • 1/1, 1/2, 1/4, 1/8, and 1/16 Microstepping.
  • Step and Direction Control.
  • Built In Protection Circuit to help against blown chips on stepper motor short or open connections.
  • 3.6″ by 4.8″ double sided with top silkscreen and thru plated holes and lead free solder PCB. (RoHS compliant).
  • Power On Reset.
  • On board voltage regulation for 5-volt logic with 24VDC cooling fan from motor power supply.
  • On board connections for home and limit switches with 10K pullup resistor provided to each. No need for a separate “break out” board.
  • Minimum of components to make assembly fast and easy!
  • Works with Step and Direction software such as DeskNC, TurboCNC, Mach3 etc

Kits requires PCB soldering skills


Parallel Port Pinouts (NOTE! Different from other HobbyCNC Driver Boards!) are as follows:
2=X step, 3=X dir, 4=Y step, 5=Y dir, 6=Z step, 7=Z dir, 10=Limit, 11=Z home, 12=X home, 13=Y home, 18-25= Ground, All others are not connected´┐Ż
