Thanks for the video! I wanted to know the functionality and approximate strength of micro stepper motors in general and this video absolutely delivered what I wanted.
You can find the schematic by searching for "A4988 stepper motor driver connection". For example, this article shows how to wire a stepper motor: howtomechatronics.com/tutorials/arduino/how-to-control-stepper-motor-with-a4988-driver-and-arduino/
Hello, is it possible to see a schematic for this? I really want try to recreate it however I can barely find any information on this specific stepper motor. Any help would be appreciated. Thank you
The A4988 stepper motor driver has digital control inputs that are compatible with 3.3V logic. Therefore, I think that everything will work out for you.
Great video! I was just browsing these on ebay and found this video. Really great demonstration of what it is capable of. Thanks! Did you figure out why it died in the end?
Great video, thanks for the explanation, do you know what is the current limit for that motor? I know you were using 5v, but I am not sure what limiting value you used for current on the Driver, thanks!
Hello. Please i want to run 32 steper motor of those kind. On a small project. Do i need to use for each it's own steper motor driver or i can just contrôle them with arduino if yes please tell me what i need to make them work. Thanks in advance.
@@NanoslavicLab yes. My problem is about controlling 32 of the same model that you have. I don't know if one microcontroller can control 32 steper motor. Or do i need to an extension to the pins.
@@oussamasmaini7297 For bipolar stepper motors controlled without a driver module you have a max of 3,3 (logic) voltage. Check your microcontroller for max current per pin. Generally this is not the best way to set this up as this will create unpredictable behavior in both motors and microcontroller, especially if you connect multiple motors. If you want to do this without driver modules you'll need 4 pins per motor. 32x4 pins on one controller is not something you'll most likely find ;)
@@NanoslavicLab I mean the durability of the motor, some small motors only last about 5 hours like for mini drones, this being a stepper should last longer but I have concerns about the gears and since the motor is so small
@@NanoslavicLab thank you so much. I spend one day but my motor didn't work. I don't know why :(( . I read the datasheet of A4988 and it said the range power supply for motor is 8v-35v. and i try this but my motor didn't work :((
In this video I have shown two driver boards - red and blue. The red one worked fine and the blue one didn't work at all. Sometimes the electronics breaks down before being turned on for the first time.

Could you add the picture of the connections in the description of the video ? It would be of a great help. Thank you.

What is the voltage applied at vmot and vdd ? Thank you
@@NanoslavicLab
I applied 5V
were you able to measure the steps per mm, or the steps per revolution?
surprising amount of power for such tiny motors.
Thanks for the video. saved me a hustle! big thanks.

I need to control this same rotary stepper with the same model you choose, but in my case I need to use Raspberry PI pico. it will be possible?

hi can i get a step file for Mini 4mm 2-Phase 4-Wire Precision Planetary Gearbox Gear Stepper Motor Stepping Motor Linear Screw Rod Metal Slider Block
What is "step file"?:)

Another stepper driver was not working. Red driver well works.
Great Video, but im having trouble understanding the schematics, could you maybe link a blueprint or a scheme somewhere? thanks
also i would like to know specs of that capacitor (voltage and capacity)
What voltage power supply did you use to power the driver board? I think that stepper is max voltage allowed is 5V
I used 5V. The stepper motor driver is current limited
With a flexible coupling and all
Yes! It is cool.. lovely “
Great video, thanks for the explanation, do you know what is the current limit for that motor? I know you were using 5v, but I am not sure what limiting value you used for current on the Driver, thanks!
I don't know what the max amperage of this motor is. I haven't even tried to find any description for this motor because I don't know the part number.
What are these used for???
lenses in cameras.
Can be good to make mecanic of the finger ?
I don't know:)
can you give me the frequency of the pulse that you supply for the motor
about 1 kHz

Thanks in advance.
In theory, you could connect a motor directly to the microcontroller pins. If the motor is low power, then this may work. But I haven't tested.
@@NanoslavicLab yes. My problem is about controlling 32 of the same model that you have. I don't know if one microcontroller can control 32 steper motor. Or do i need to an extension to the pins.
@@oussamasmaini7297 have you solved your issue? I was thinking about similar thing and wanted to control micro stepeers without stepper driver

Hi thanks for the video, do you know how many hours something like this can last?
What do you mean?

It looks reliable. I think, if there is no big effort and strong shaking, it should work for a long time.
@@NanoslavicLab thanks for the replies and for the video itself, I appreciate it and I subscribed :) have a nice day

Can you alter the speed at which one cycle occurs for this motor? (New to this)
I need experiments with this🙂 Soft start is possible
of course, just change the value in the arduino code ("sketch")
you get error because of the backlash, correct it in code or easier with a spring.
What is backlash and how does a spring help?
What is the force of this beast? Looking for ~ 100N. Thanks
wow. you'll have to step it down by about 100 to get that. Even after the gearbox it was probably only 1 N
Can you give me the code that you use in this video, please.
Do you need code to generate simple pulses? This is one cycle of set 1, delay, set 0, delay.
@@NanoslavicLab thanks you. Did you use 5V power supply for both logic driver and motors ?
Yes. I set output current about 200 mA on stepper driver board.
