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

We've added to our new parts listing the 8212 Maxim Voltage Monitor, the dual AA & AAA battery holder, and the new 1F 2.5V aerogel capacitor. Of them all, the new super-capacitor is pretty cool...
Freeduino, Freeduino, Freeduino!
The whole 'duino thing is just so much to say, we've got to do it three times. Blame Jerome, our intern... We've got Freeduino version 2.2 back from the assembly line today, and all tests out beeeautifully! New features include an SMD-mounted 16MHz crystal, better power-consumption circuit routing (for battery-operated projects), and "hacking pads" for […]
