To get the reference schematic in terms of nRF5340 + nPM1300

[sangyun.kim]

I'm an engineer to develope smart ring, it's a very small devie and need to use very small IC.

I'm looking for nRF5340 + nPM1300 reference schematic for this development. or good for me if there is any reference schematic nRF54L15 + nPM1300.

You can look at our Development kits, they use some combination of the parts.

The nRF54L15 development kit uses both the nPM1300 and the nRF54L15 so that can be a good place to start, but we dont use the smalest package variants there and its not the nRF5340 that is the main chip there. The nRF5340 on the DK here is a debugger MCU so not the exact same setup. 

Another option is to look at the Thingy53, it uses a different nPM but still similar.
