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

K SMD Motor Driver

Got a new kit for you - the K SMD L293D Motor Driver. No, no, the SMD isn't "surface mount" - it's the Secret Motor Driver! This L293D-based motor driver fits secretly inside most standard servo cases like the Futaba S3003/S148, and our own GM4 gear motors. It replaces the low-voltage original electronics with LED-indicated, […]

Introducting the CMDR Shield for Arduino

Last week we beefed up the Ardweeny with the Multipack, and this week we're turning out attention to the Arduino. We've just released the CMDR (Compact Motor Driver) Shield, which lets you bi-directionally drive two gear motors or a single stepper motor, read 6 analog sensors, and control up to 8 servos all at the […]
