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

Help! It's getting colder outside and the trees are starting to shed all over everything. It's quite a mess. It's pretty, but a mess all the same. So we did what anyone would do in such circumstances - we made a small DIY tank platform wirelessly controllable, released a new breakout board, and put together […]
