Stepper Motor, Small Reduction, 512 Steps, 150g.cm – Adafruit 858
This stepper motor is great for small projects and experimenting with steppers. This motor has 8 steps per revolution, but because of the 1/64 reduction gear set, this translates to 512 steps per revolution. The shaft is flattened so it’s easy to attach wheels, gears, etc, with a set screw.
Specifications:
- Unipolar stepper with 0.1″ spaced 5-pin cable connector
- 8 steps per revolution
- 1/64 geared down reduction
- 5V DC suggested operation
- Weight: 37 g.
- Dimensions: 28mm diameter, 20mm tall not including 9mm shaft with 5mm diameter
- 9″ / 23 cm long cable
- Holding Torque: 150 gram-force*cm, 15 N*mm/ 2 oz-force*in
- Shaft: 5mm diameter flattened

Getting Started:
To use with the Adafruit Motor Shield, connect red to ground (middle), orange and pink to one motor port (say M1) and blue and yellow to the other motor port (say M2). So in order, thats: orange – pink – red – blue – yellow. Then just use the example code that comes with the Adafruit Motor Shield library and set the constructor to Adafruit_StepperMotor *myMotor = AFMS.getStepper(513,motornum) and the speed at 5 RPM by calling motor->setSpeed(5). Otherwise, you can also wire it up with some transistors and use the Arduino Stepper library <Stepper.h>

I had the motor the next day. It could be just the thing I need. I will know when I get it powered up but I cannot see why it is not just what I need. Many thanks. I’ll be back!

I used this to explore possibilities for a project without purchasing (and possibly not being able to use) a more expensive motor. I modified it to be bipolar and it works a treat with the small H bridge controller.
