Drives any 5, 6 or 8-lead unipolar stepper motor rated up to 6A (5 - 35Vdc) in either Free-Standing or Computer-Controlled mode for CNC type applications.
Free-Standing mode provides motor speed control using an onboard trimmer and direction control is via an onboard switch. (internal oscillator)
Computer-Controlled mode provides direction and step control using pulses from the computer parallel printer port and can be used with a wide variety of CNC control software packages. Up to six 3179 driver boards (for controlling 6 motors) can be connected to a single PC parallel port.
Uses IRFZ44 power MOSFETs to drive the motors. These MOSFETs have a low on resistance and can carry 6 Amps each without a heatsink. Uses discrete logic ICs (4013, 4030, 4093).
Separate power connections are provided for the board and motor supplies. Screw terminal blocks and solder pins for connections.
