Review: cool little motors - bought a handful and tested one on an arduino (no special driver, straight from the pins) and it works great.
Review: Doesn't work - Like one of the other reviews mentions, it just gets hot, doesn't ever turn.

## Features

- New micro 2-phase 4-wire 4mm stepper motor,with planetary gearbox(the outer diameter is only 4.25MM), and its planetary gears cannot be seen clearly with the naked eye. It can be distinguished by using an enlarged mirror. The entire metal slide is also very precise and stable.Connection of motor, gearbox and metal slide,all using laser welding points, is very precise and sturdy.
- The motor drives the precise skewed lever to move the metal slider up and down.
- The brackets are basically made of metal.
- The spindle is made of ultra-fine precision ball bearings.
- The difference between model A and B is just the length of the cable. The stepper motor, reducer, and metal slide are all the same.

### ⭐⭐⭐⭐⭐ cool little motors
*by A***M on March 10, 2021*

bought a handful and tested one on an arduino (no special driver, straight from the pins) and it works great.

### ⭐ Doesn't work
*by S***. on May 12, 2022*

Like one of the other reviews mentions, it just gets hot, doesn't ever turn.

### ⭐⭐⭐⭐ Works with correct wiring
*by A***. on December 17, 2023*

The image is labeled incorrectly. Swapping the B+ & B- pins gets it moving, as the traced image I’ve attached shows. Fun little linear stepper! I recommend shutting off power to the pins any time it doesn’t need to move, or it’ll just build up heat. This design holds position with no power applied. I’ve used this with an Arduino Uno, straight off pins 2,3,4,5 and the example sketches “Constant Speed” and “Bounce” from the default stepper library.
