Circuit: Stepper Motor

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:

  • 74AC240 Octal buffer chip
  • 4 x CP0.1µF capacitors
  • 100k resistor
  • 2 x 47k resistors
