Note: To program and debug the nRF52840, nRF52 needs to be selected on the PROG/ DEBUG switch (SW5). Since this firmware in the nRF52840 decides the nRF9160 DK behavior, it is vital that it is always present in the nRF52840. If it is accidentally erased or firmware affecting the use of the key nRF52840 GPIOs is programmed in, nRF9160 DK functionality is not guaranteed. -

The LEDs are active high, meaning that writing a logical one ('1') to the output pin will illuminate the LED. The nRF9160 GPIOs control power transistors and LEDs are fed from a separate 3.3 V domain. Therefore, LED current will not be drawn from nRF9160 GPIOs or the nRF9160 supply. -
Page 23: Debug Input And Trace Options
5.9 Debug input and trace options The primary debug interface on the nRF9160 DK is the Segger OB debugger available through the USB port. However, if other than USB supply is used on the board, this functionality will be disabled. -
