Hi Nivethitha,

1) Is it possible to program and read data in nRF5340 using USB lines?

Yes, it should be fine to program using the USB lines. You can take a look at the reference schematic for the nRF5340DK.

2) Is the below schematic correct for our requirement do we need to add anything else?

In case you are using the USB, you need to make sure to connect the VBUS as well as DECUSB according to the reference schematic.

Hi Priyanka,

 We are using  WT02V40V in our design. DECUSB 

Could you make sure if we can debug using these USB  lines?

[Nivethitha]

Also, How to program using USB. Could you elaborate the procedure?

Hi Nivethitha,

Please go through the USBD documentation for further details.

Please also take a look at the 5340DK reference designs for connections and layout.

You can also go through the nRF Desktop application which utilizes the USB module.
