Drives any unipolar (5 or 6 wire) stepper, 12 to 36 Volts up to a solid 10 Amps (but add heat sinks). Optoisolated input signals to protect your computer - completely separates logic and motor supplies. 69 x 25 x 20 mm high (2.7 x 1 x 0.8 inch).
Easy interface to your PC's parallel port. We even include a BASIC code listing for running a stepper from your parallel port. Easy, useful and educational!
Motor Supply voltages over 20 VDC require the addition of a zener diode (not included), and your application may also require heatsinks.
