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

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

I would give a more thorough review as I just received it and will probably not be able to utilize the stepper motors in a project until later in the year.

Had so much fun using the stepper motor. Works well however they dont last. I guess the price!

Love these little motors. These arent designed to be use in any kind of 3D printer or CNC applications though. They have enough torque to be use on linear slides and camera mounts however. I use them for automated door locks using a NodeMCU and their fantastic. I also use them with a Arduino Nano and a joystick or with an IR sensor and any remote. Basically dont use them on anything that needs to constantly be moving, they will get too hot and their performance will be reduced or they may even skip steps.

good price for the four motors, now time to work on some projects with these.

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.

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

Schnell geliefert. Produkte perfekt!

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.

Not vary powerful but for the money they are great
