18° Micro Stepper Motor for Arduino

A compact 10 mm micro stepper motor with 18° per step, designed for direct connection to microcontrollers like Arduino and ESP32 without requiring a dedicated driver board. The 2-phase 4-wire bipolar configuration makes it straightforward to integrate into small-scale automation projects.

The motor features a metal slider on the slide rod, making it well-suited for linear motion applications such as automatic door locks, camera mechanisms, and DIY smart home devices.
