XYZ Stepper Motor Driver Board

XYZ Stepper Motor Board Photo (not exactly as shown)


  • 3 separate channels (for bi-polar stepper motors)
  • up to 2 Amps per channel (with adequate heatsinking)
  • based on L297D chopper stepper motor driver and L298 dual H-bridge chipset
  • set motor current independently via trimpot for each channel
  • H-bridge packages mounted along board edge for easy heatsinking
  • accomodates two limit switch inputs per channel (six total)
  • includes on-board 5V regulator
  • AD12DX form factor (3.25" x 3.25") x 1.0" high
  • all control signals on standard 50-pin connector pattern
  • control it with anyAdapt11 or Adapt12 family board
  • or control it from your PC, via our Parallel Port Interface (PPI) adapter (see below)
  • 12 connector options for the ultimate in modular design capabilities
  • Order Online at


The XYZ Stepper Driver Board:

The Parallel Port Interface Board:

  • interfaces the 3-Axis Stepper Driver board to your PC's parallel port using a standard (user-supplied) DB25 extension cable
  • has on-board 5V regulator (you supply external unregulated DC of 9 to 12V at 0.5A)
  • you supply appropriate motor voltage to the driver board (Caution!  switch motor voltage on only after your PC is running!)
  • mates with the 50-pin connector of the driver board, above
  • information and PC driver shareware for implementing a CNC machine available here
  • DeskNC for DOS and other useful software are available here
  • for a hands-on project, refer to the four-part CNC article in Nuts & Volts magazine (starting with the May 99 issue)
  • schematic diagram included
