Series, and nRF70 Series System on Chip (SoC)s and nRF91 Series SiPs. The interface MCU on the nRF9151 DK runs SEGGER J-Link OB Debugger interface firmware and is used to program and debug the firmware of the nRF9151 SiP by default. - Page 22 Hardware description Figure 19: Connecting an external board to P19 It is recommended to power the external board separately from the DK. The voltage of the SWD interface on the external board must match that of the DK. The default voltage is 1.8 V. When the interface MCU detects GND of the external board on pin 3 (SELECT) of P19, it programs or debugs the target chip on the external board instead of the onboard nRF9151 SiP.
