  * In debug configurations, logs are provided through the UART.
  For detailed information on working with the nRF54L15 PDK, see the :ref:`ug_nrf54l15_gs` documentation.
  * The configurations use the MCUboot bootloader built in the direct-xip mode (``MCUBOOT+XIP``) and support firmware updates using the :ref:`nrf_desktop_dfu`.
+ * The board supports the ``debug`` :ref:`nrf_desktop_bluetooth_guide_fast_pair` configuration that acts as a mouse (``fast_pair`` file suffix).
