NRF52832 Breakout board


I have been stuck on this issue for a long time, I have created a buetooth mesh network using NRF52832 IC, which I have completed perfectly.

But the issue is I want to create its standalone PCB design. I have asked this question before and someone replied there that I am using 3rd party components but this NRF IC belongs to this company.

I have designed the PCB design myself but one it gets heated, if run for a long time and secondly, one of those boards gets burned up. Problem is in circuit designing somewhere.

So, can someone helpme out here, I am posting it again, may be some guy with hands on this IC, could help me out here.

Here's the ref board: I am trying to design exactly the same thing but in small size with mini USB port.
