3.8V stepper motor: lightweight and easy to install

This small Pololu stepper draws 0.67A per phase, allowing for a holding torque of 600 Its compact size and light weight allow it to be fitted into any project requiring a stepper motor type device (3D printer, hard drive, linear actuator, etc.).

The motor has 4 wires (2 per phase: black/green; red/blue), all terminated with bare leads. You can control your motor using a pair of H-bridges, although we recommend connecting it to a dedicated stepper motor controller.
