Can I power Arduino Uno using 12V 0.8A Power supply and one sensor?

Good day! I was hoping that I could use my 12V 0.8A stepper from 5V 2A power supply (Power bank) to my Arduino project. I'm using one sensor which required voltage is 12-24V.
Can I use my existing power supply to power my arduino uno and my sensor?

List list the pieces that you say you have:

  1. a stepper motor that has a minimum requirement of 12 volts and needs 0.8 amps to run.
  2. a 5 volt supply that shows it may be capable of 2 amps
  3. some sensor that requires 12 to 24 volts to operate.

Can you show a block diagram how you intend to connect this all together and power it from your 5 volt power supply? Where will the 12 volts for the two devices that need 12 volts come from?

I mean I have a power supply (a powerbank) that has 5V2A output and Im using a stepper voltage 12V 0.8A so that I can use my sensor which required 12V.
Im using MAX485 (5V requirement which can be powered using arduino uno).
Sensor which required 12V
and arduino uno.

Please pick where you post with a lot more chair. Installation and troubleshooting is not for your project. It is to get the system working.
So I have moved your post here.

By the way I can’t make any sense about what you are asking.

Around here "stepper" means a stepper motor.

I think what you actually mean is a step-up (boost) DC-DC converter. If you post a link to the thing you're talking about we can be clear. But if I'm right then you should probably be o.k.

So how do you propose to change the 5V output into 12V?
Or is that your question?

Thanks that could make sense. Using the wrong words is a great way to cause confusion.

Hi im sorry for the confusion. It seems @slipstick is correct in step-up voltage.
And he answered that I'll be probably o.k using the 12V0.8A for my Arduino uno.

:rofl:

Auto-correct drives me nuts too. Voltage to village for example. Debounce to denounce...

Hello @slipstick , the microcontrollers are working fine this last 2 weeks and being powered by power supply. It was still working last night, but now the Arduino uno won't send into serial when being powered by a power supply I used which is a 12V 0.8A, but when I used the usb cable to power the Arduino uno sends data to serial just fine.
