Thank you, ...
After turning on the power,
I did not connect anything on the board.
but it is about 2.7 volts out of the pin (p0.04).
It was almost zero volts before,
but the output...
In my design the nRF52 is connected to an STM32 host MCU. I connected the UART for data communication and the SWD and RESET pins for programming.
The nRF52 needs to be programmed...
