Circuit: Stepper Motor
Dave Hrynkiw
July 12, 2007
This is a neat little one-chip circuit we originally tuned for use with our "SM1" Stepper motors. We've presently sold out of the motor, but this circuit has proved to be a good unidirectional (1-way) driver for small stepper motors. Parts required are:

- 100k resistor
- 2 x 47k resistors
