Features 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 any Adapt11 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 http://www.technologicalarts.ca/index.php

Resources:

• L297D and L298 data sheets, and ST Microelectronics Application Notes 1679 and AN470 are available online

• fully assembled and tested module (Rev. 2)
• includes full schematic, pinout and dimensional drawing
• module supplied with -F-F connector options (unless requested otherwise)

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
