ELEGOO 5 Sets 28BYJ-48 ULN2003 5V Stepper Motor + ULN2003 Driver Board Compatible with Arduino

Great motor, works well! I use it in my lab to move a translation stage, so it gets quite a bit of use. The motor runs hot, but a simple fan is sufficient to keep it running for multiple hours at a time. Would buy again!

Update: Elegoo took care of the issue I had very thoroughly. Changed rating to 5 stars for excellent customer service. I will continue to make my purchases through them. [Original review] These little stepper & driver boards are GREAT for learning your way around programming. Arduino libraries are a little under gunned for these driver boards; accelstepper works much, much better. I suggest running at 6 volts or better, as under that I cant seem to get the little guys to really run. The boards are rated from 5-12VDC. Fried one in seconds at 10v (although the motor ran quite smoothly & with sufficient torque to actually use). No torque or speed really to speak of, but hey, theyre cheap. Good learning tool. Will contact Elegoo for a replacement.

I have no idea what these could be good for as they have no torque and they get smoking hot. I consider them junk.

Of the 5 ULN2003 boards, 4 had bad leds. One board had zero working leds.

Highly likeable. These work as expected. Dont expect a great deal of pep out of these; they are geared to provide torque more so than speed. At 12v, these get quite toasty, so Id recommend using 5v.

Great for what I needed! Easy 5o code on an Arduino and worked with my Arduino nanos too.

These are good, make sure you wire it correctly. Stepper myStepper(stepsPerRevolution, 8, 10, 9, 11); worked well for me. Basically swap the middle to pins and keep it to 17 rpms or below. Pretty Decent value.If you want to save space or use fewer micrcontrollers, you can run this guy with a NE555 and a CD4017 decade counter. A frequency of about 90 HZ on the 555 50% duty cycle works pretty well as a starting point. Update: use accelStepper configured in as AccelStepper::HALF4WIRE. Can get it up to a max speed of about 1000 pulse per sec as max speed

Worked fine in testing. I havent used them for a project yet.

I will be using these motors for self stirring cauldrons for a Harry Potter fair.

Delightful little motors. Operation is a simple walk: 1 foot down, 2 feet down, and so on like: | In 1 2 3 4 / In 1 2 3 4 | In 1 2 3 4 / In 1 2 3 4 | In 1 2 3 4 / In 1 2 3 4 | In 1 2 3 4 / In 1 2 3 4 Where a foot on a pin is a high voltage on that pin; its requires a bit more of the cpu than a direction_pin, step_pin setup, but I like the more direct understanding of the phase. Operation is very smooth with the 64x gear reduction even before trying microstepping. Planning to use this to motorize the stage of my labs microscope so we can automatically optimize alignment between its laser vibrometer and reflective targets.
