BYJ48 STEPPER MOTOR
Stepper Motor is a type of electromagnetic device which moves in discrete steps. This has several coils, the center shaft has a series of magnets mounted on it, and the coils surrounding the shaft are alternately given current or not, creating magnetic fields which repulse or attract the magnets on the shaft, causing the motor to rotate.
This Unipolar Stepper Motor 28-BYJ48 is provided with five wires and four coils. The center connections of the coils are tied together and usually used as the power connection. They are named unipolar steppers because power always comes in on this one pole.

Although they are not super fast, I can't think of all that many applications when you would want a super fast stepper motor. With the amount of torque these have, you could gear it up anyway. I vaguely recall someone mentioning they were geared down inside the box, which seems plausible because the number of motor steps differs from the number of steps per revolution by like 32 or something, but honestly I can't remember. Sorry. If I end up taking one of these apart someday, I'll update.
I won't take the time to make actual measurements for torque and speed because datasheets seem pretty readily available for these motors.
The mounting holes are well placed and the cable is very convenient for quick and easy solderless connections. The motors are very sturdy and show no signs of wear despite my relentless abuse (on account of the low price). 5 Is a good number in a set.
The ULN2003 driver modules are nice both for quickly testing and even for final installation, provided you are not strapped for space. The LEDs are useful for troubleshooting if you don't have much experience with stepper motors. In fact, if you don't have much experience with stepper motors, I highly recommend this set. It's cheap, versatile, and super easy to use. It's also convenient that these run on 5V.
I think these take something like 500mA depending on speed, load, etc. , but I can't really remember well so that may be completely wrong. In any case, these are too big to run safely on the 5V pin of an arduino.
All around, I highly recommend these stepper motors (or equivalents from other retailers) for a multitude of uses and there is a very good chance I'll be buying more of these in the future.
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 wouldn't be fun without that. It's nice that the board and motor are together so we don't have to guess if they'll cooperate.
I understand the tiny motor controller boards work with a wide variety of stepper motors, so it's great that we have a pluggable connector instead of wires soldered on. We will be using that. I'll probably be scavenging steppers from inkjets and scanners for months. They work with all the little programmable boards that make GPIO, so they'll be fine with a Pi Zero when we put them in service. But we'll develop on the Pi3.
You're not going to get a lot of RPM out of these. That's not what they're for (and, specifically for our first application we're gearing down to 7*10^-4 RPM obviously). Also, these are not industrial stepper motors for your production line. And they're 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:
UCTOP 80Pcs Plastic DIY Robot Gear Kit Gearbox Motor Gear Set For DIY Car Robot
The "D5" gearhead (the blue gearhead with the largest bore and a flat) fits diametrically, though the flat is not deep enough. I'll be filling that gap with epoxy, and it will work just fine. You can get a number of setscrew 5mm bore heads for your project. There's one with "timing belt" that looks interesting. It would be nice if someone with these motors and a matching gear set would post a review so we know what to buy. The seller of the motors, maybe? If it was me I would put the ASIN of the matching gears right in the product description, as it would help to move product - or even sell the gears myself.
I happened to order some jumper wires in the same order. These saved a lot of time. Whether you're connecting to a male header on the Pi or your breadboard, there's a set of jumpers just right. These things are precious. You just peel off however many leads you need.

Is what it says, slamming deal, excellent delivery. Would buy again.
Nevertheless, they'll be good for learning how to control stepper motors and for places where accuracy isn't too critical. They aren't particularly strong at 5V and tend to stall out under light to medium loads. Despite their voltage rating, they run perfectly fine at 9V (Do so at your own risk!) and are definitely more powerful, but get much warmer, as to be expected. They are a bit noisy due to the gearing, but are definitely on the quiet side when it comes to steppers.
Overall, they're a good starting point for stepper motor control, and perhaps even small robotics applications. And for the price, they're pretty good at what they do. Plus, the plastic box they include is handy for storing the motors, or other projects.
