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

Works with correct wiring
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.

It isn't turning, might be me
So far I haven't been able to make this move. It just gets hot. The windings still measure 14Ω so I'll assume I haven't burned it out. I'm using an A4988 step-stick that is also new to me, so it might be operator error...I'd give it one more star if it came packaged better and with a bit of printed data in the package.

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

It works with enough hours
The stepper works with the A4988 driver board (given enough patience).I couldn’t get it to work on a L9110S driver or off GPIO on a pico.The motor is pretty loud, but has been reliable so far despite getting very hot (100 C -ish) when current is not cut off by disconnecting the a jumper between SLEEP and RESET with a transistor.From driver board to motor the correct connections are:1B to A+1A to A-2A to B+2B to B-.It’s a good hobbyist linear actuator.

Don't waste your money
I bought this for a mini pin plotter I built. It worked great... for ten minutes, just enough to print "Hello World" the next print it failed and when I tested the motor it was dead.

Worked perfectly. This is a mini unit
Very smooth operation.Perfect for small moving projects.
