they work and cheap and look like have enough power for my application, possible high power draw...
Updated:
This is my very first stepper motor outside of college 20+ years ago :-)
Here is the link to more tech details https://components101.com/motors/28byj-48-stepper-motor
I would use separate PS for these motors, some examples out there show you to connect power from Arduino itself.
I made 2 motors run using a single loop with a count down and "if(t%delay==0) do one step;" logic. It takes 4096 steps for complete 360 degrees and it does take some time as we are delayed at least 31 microseconds per step. With a shorter step cycle, the motor would not move, I think you can do gradual speedup once in motion which I did not try.
One thing I noticed and I will investigate further later, my PS got real hot real fast while running both motors. If I read my el-cheapo meter correctly (surely my good meter is in the car) it was drawing almost 1 amp... reading was not stable as PS kept cutting out and my meter was powered by the same PS as the circuit... no shorts I checked.
Well overall for ~2$ per motor and driver board and some jumpers (almost enough for 2 motor connections) it is an OK deal. Not sure if there is a better option which would save me on a battery and move faster at the same time. Btw boards seem a bit crude but 2 out of 2 worked so far.
Anyway, I recommend this for project work, learning and prototyping. I hope to get my 11 YO to try and make a working clock, but he prefers video games :-(

High torque 5V stepper motor
Its torque is pretty high with a 5V power supply from Arduino Uno. My finger cannot stop its rotation. Its rotation speed is about <12RPM (just estimation), pretty slow, but just perfect for my project. It works with 3.3V too, but its torque is much lower. My fingers can stop its rotation when using 3.3V power supply. Very easy to setup up. Search for "Arduino - StepperUnipolar" for more detail how to set it up with Arduino code. By the way, it has 5mm shaft, consume about 160mA with 5v. Just for your information.

Great product, easy to use (plug and play)
Great product, easy to use (plug and play). No issues with accuracy. Fast enough for my uses.
I was also impressed by the container in which it came. As an amateur roboticist, any help with organization is great.
cant complain about the price.

Works Great, step speed must be slow though.
I built a computerized focus for my telescope with these. You need to keep it at around 75 ppm to get good stepping without any missed steps. 250 ppm will be very inaccurate, 125 does alright, but for me 75 ppm at full step worked amazing. Worth the money for sure.

Reliable. Good value.
I am using these for an Arduino project in my computer science class. This is a nice stepper motor set at a good price. Works out to be about $2.75 per motor/board set. Storage box is a plus. I have bought other Longrunner parts in the past including other servos and motors and they have not disappointed me.

Question & Answer
Question :
How much weight can this thing lift?
Answer :
According to the spec sheet, this stepper motor is rated by torque values. The torque values are measured in units of gram-force * cm (g-f * cm). For example: with a 15g weight hanging on the end of an arm 10cm from the motor shaft, the corresponding weight would be calculated 10*15 = 150 g-f * cm of torque. These little 5V stepper motors are probably good for 170-190 g-f*cm pull-in (step) load max, and 950-1050 g-f*cm pull-out (holding) load max. Hope this helps.
Question :
Do these work with raspberry pi 3?
Answer :
The product is just 5 5v unipolar stepper motors and 5 ULN2003AGP motor drivers. Nothing special about them and can therefore be controlled by any device capable of outputting the required step pulses - including the Raspberry PI 3. Check out this link https://learn.adafruit.com/adafruits-raspberry-pi-lesson-10-stepper-motors/overview for more info, it uses a different driver put the concept is the same with the ULN2003. There are many other sources on driving unipolar steppers with ULN2003's, just use your favorite search engine and adapt what you find to the PI.
Question :
Can these be used for a 3d printer
Answer :
I don't think so. These motors do not have that much power.
Question :
Can this work with an Arduino Nano?
Answer :
Yes, it can compatible well with Arduino Nano.
Question :
No output shaft diameter and length are given in the product information. Can anyone answer?
Answer :
Hmmm.... I don’t have an exact measurement but I follow a rule of thumb that three times about the length of the output protrusion plus a relative length you can gleam.... in this case I think it’s around an inch (2.54 cm) but to safe go for a little less (like 2.5 cm) time three and that’s probably the max. As for the diameter I guessed it about 1.2 cm. I just wing it :D.
Question :
To the seller: hi ! i am looking for the 24byj28 8v stepper motor, but can't find it. do you happen to have it on stock?
Answer :
Thank you for your question. We only have 28BYJ-48 stepper motor on stock.
Question :
What input voltage levels are required on in1, in2, in3, and in4? is it a level or pwm.
Answer :
The input is high and low.
Question :
Is There a mechanical spec sheet available?
Answer :
Yes, you can get it by email. Please be free to contact us.
Question :
Is the reduction ratio: 1/6?? Not 16:1? Not 64:1?
Answer :
The reduction ratio is 64:1.
