18° Micro Stepper Motor for Arduino

This 10mm micro stepper motor delivers 18 degrees per step across a 2-phase 4-wire configuration, making it ideal for hobbyists, students, and makers building compact motion projects. It connects directly to 3.3V and 5V microcontrollers like Arduino and ESP32 without requiring a dedicated driver board.

Direct microcontroller drive

The motor runs directly from standard controller pins on boards such as Arduino and ESP32 without needing an external driver board. It operates reliably across a DC 3.3V to 5V driving voltage range using bipolar drive.

Integrated linear slider rod

A metal slider mounted on the threaded shaft translates rotational steps into linear motion with a maximum thrust of 80g. This mechanism is suitable for miniature mechanisms such as DIY automatic door locks, camera sliders, and smart home devices.

Four-wire pinout interface

The 2-phase 4-wire wiring supports 2-2 phase excitation with a coil resistance of 20 ohms (plus or minus 10%). It provides Class E insulation with a withstand voltage of 100V AC for one second.

Precision dimensions and stepping

The compact 10mm unit achieves an 18-degree step angle with a minimum auto-start frequency of 1500 PPS. It is designed to operate in ambient temperatures ranging from -10 to +60 degrees Celsius.

Package contents

The package includes one 18-degree micro stepper motor ready for direct connection to compatible microcontrollers.
