Hello everyone,
I am trying to measure the current being consumed by nrf52840 using an external power supply.
Setup: I have connected 3.3V DC power supply to connector P21 and switch 10 is in ON position and switch 9 is in VDD position. As specified in the picture below.
However, the board is not running with this setup.
As mentioned in the second screenshot, supply VDD domain from a different source, I tried connecting USB to power the remaining board. But it does not work.
Kindly help me understand how I can power the rest of the board? If I have to power the rest of the board with USB what extra changes do I have to make on the board?
Regards,
Sameer
