The debugger contains a board controller that controls the power supply voltage and signals which enable and disable features on the nRF54L15 DK.
All features on the nRF54L15 DK have a default factory setting when they are dispatched from Nordic. The default setting is applied at the first boot. The configuration of the board controller can be changed through nRF Connect for Desktop's Board Configurator application. If the configuration is modified from the default factory setting, the board controller loads the modified configuration every time the nRF54L15 DK is restarted.
For more information, see Board Configurator app.
