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

A great prototyping/experimenter kit. The motors are clearly designed for light duty but well-made and suitable for many projects. The packaging and driver boards make this a must have for anyone wanting small steppers for Arduino, Pic, or Raspberry Pi projects. The price is reasonable for the combination pack. In general, Ive been pleased with Elegoo products, including this kit.

Just what my grandson was looking for. He has built a number of projects using them.

Great value for the price

The internal plastic gearing is a little too weak, but that was too be expected. Surprisingly accurate for their low cost. I would recommend these for non strenuous prototyping. All around, great for the price and the came all working, in great condition.

Works fine

Great stepper motors for learning to control steppers with an Arduino. Inexpensive, plenty of torque and decent (though a little slow) speed. they seem to be accurate enough and repeat without any noticeable slipping. They require 32 steps to get the internal rotor to make a full revolution, and the rotor is geared down 64:1 to the rotation of the outer shaft. That means if youre using the stepper.h control from the Arduino library it will require you to enter a value 2048 in the number of steps line in order to get one full revolution of the outer shaft. And at least for the motors I received, 15 RPM seems to be about the maximum I can get out of them. They do run a little hot, but not excessive. Power them with a separate (not the Arduino power) 5V DC power supply and they work great.

The product is very good, great for students

As advertised, nothing really to say about it good or bad

Used these stepper motors/drivers with an Arduino Uno to focus a telescope. Although theres some backlash in the gears the 64:1 reduction provides quite a bit of precision. They work great.

Good price. Decent motors
