How can I get the value ​​from the board that has dm dp gnd vbat pin Using with arduino nano

Welcome to the forum

You started a topic in the Uncategorised category of the forum when its description explicitly tells you not to

Your topic has been moved to a relevant category. Please be careful in future when deciding where to start new topics

As to your question, what value do you want to get ?

Please confirm that you have a Nano classic board and not another of the many "Nano" versions

What are the dm and dp pins that you refer to ?

I am using arduino nano board which I have found information about dm dp pin is usb pin and I want to get value from this board how can I do that?

Please post a link to where you saw this

Where is the data coming from ?

Sorry but I can't remember which forum post this was.

Want to get values ​​from a board that has dm dp pins.

Please explain exactly what you want to do

Are you trying to read USB data or just the state of the pins, for example

I want to get the pressure value from the pressure meter board with dm dp pin, how should I do it

Is the pressure meter using the USB interface ?
Please post a link to the pressure meter

Now I want to know what are the dm dp legs and how to get the values ​​from them.

Pin 2 is the negative data terminal denoted as D– (DM), while Pin 3 is the positive data terminal denoted as D+ (DP) . These pins make up the differential pair that carries out data transfers

Does that help ?
I suspect not

So how can I use it with an arduino nano to get values ​​from these pins?

@UKHeliBob , I was hoping that’s what he meant.
I doubt OP has the skills at this time to move any further.

I'm a newbie.

It sounds like you are trying to create your own USB Host. If so then you would be better off using a board other than the Nano

Search Google for "arduino as usb host" for details

Can I use the esp32s2,s3 board with pin 19,20(d- d+) connected to the pressure meter board to get the value?

You cannot directly read a negative voltage using a pin on the ESP32

In any case, do you know what format the data is in on the two USB outputs ?

I read it from here Esp32 S2 connect USB device and send data but I don't really understand it.
