In nRF9160 DK revisions earlier than v0.14.0, nRF9160 signals routed to
other components on the DK are not simultaneously available on the DK
connectors.
When compiling a project for nrf9160dk_nrf52840, the board controller firmware
will be compiled and run automatically after the Kernel has been initialized.

When building for the DK revision 0.14.0 or later, you can use the following
additional nodes (see :ref:`application_board_version` for information how to
build for specific revisions of the board):
