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

Good kit of inexpensive motors for a small project.

Simple interface to Arduino. Easy to program. The high resistance of the windings mean you dont have to do anything complicated to make them move. No H drive, PWM or current control required.

nice product

It was fun working with these motors, great quality!!

Worked for the project I intended to do. Not much flexibility on operation especially the board.

Just did a breadboard with the sample code from this page and tried all of the steppers in it. Three of the five only turn in one direction and simply shudder when trying to turn in the other direction. Two of them work in both directions as expected. After fooling around with these on my Raspberry Pi Zero W2, I found the real problem is the 800 microsecond delay in the code, it is too small - bump it up to 900 and all five of the steppers work fine.

I bought these motors for a Raspberry Pi star tracking telescope project. Im doing hacker stuff with my daughter. Got the 5-pack because hey, theyre not costly, well want to make many other projects anyway. Plus, we dont want to be afraid to let the magic smoke out of our Only One critical component so we always get several. We also like to test the limits of devices and the only way to find the absolute maximum limit is to go just a little bit more. The tested motor and board is as described in the listing. I drove it straight from the +5V pin of the Pi3, which is strongly not recommended because excess current draw might reboot your Pi. Torque is great for such a tiny motor. I was able to google the necessary information and operate the motor in Python with my Pi3 in just a few minutes. Some minor adaptation of the available information was necessary for our specific workflow - which is the hacker life. It wouldnt be fun without that. Its nice that the board and motor are together so we dont have to guess if theyll cooperate. I understand the tiny motor controller boards work with a wide variety of stepper motors, so its great that we have a pluggable connector instead of wires soldered on. We will be using that. Ill probably be scavenging steppers from inkjets and scanners for months. They work with all the little programmable boards that make GPIO, so theyll be fine with a Pi Zero when we put them in service. But well develop on the Pi3. Youre not going to get a lot of RPM out of these. Thats not what theyre for (and, specifically for our first application were gearing down to 7*10^-4 RPM obviously). Also, these are not industrial stepper motors for your production line. And theyre not going to drive your electric vehicle. People are asking questions about the gearsets to use with these. My motors came with a 5mm axle, double flat. Previously we bought a plastic gear set through Amazon:

Excelente producto.

Was a little unsure what was included based on picture. Contents exceeded expectations and included storage box,

Price is good, but motors are poor torque
