Max Output Current: 0.5A (Single Output)
4 LED indicators
Size: 40.5mm x 21.3mm
Stepper Motor Cable Length (approx.): 24cm
Holding Torque: 0.3kg/cm
Diameter: 28mm
Step Angle: 5.625 degrees
Reduction Ratio: 1/64

  5. This is an example of how to use the HobbyComponents Arduino compatible stepper
  6. motor with driver interface (HCROBO0055) . When run this program will
  7. continually
  8. rotate the motor one full revolution in the forward direction
  9. followed by one full
  10. revolution in the reverse direction. Although this stepper motor will
  11. work with the
  12. standard Arduino stepper motor library functions, this program
  13. demonstrates how easy
  14. it is to directly control.

If you mean a schematic, I've just added one to the first post.
