Your PCB was manufactured, but it does not work as expected?
I will review, troubleshoot and redesign your schematic and PCB to identify the likely root cause and prepare a corrected design for your next prototype or production revision.
Maybe:
The board does not power on.
The MCU will not boot.
A regulator gets hot.
The sensor does not respond.
USB is unstable.
