+DA14695 Development Kit USB
+###########################
+
+Overview
+********
+
+The DA14695 Development Kit USB is a low cost development board for DA14695.
+The development kit comes with an integrated debugger and an USB hub
+to have both the on-chip USB and the J-Link connected via a single port.

+
+Hardware
+********
+
+DA14695 Development Kit USB has two external oscillators. The frequency of
+the sleep clock is 32768 Hz. The frequency of the system clock is 32 MHz.
+
+Supported Features

+
+System Clock
+============
+
+The DA14695 Development Kit USB is configured to use the 32 MHz external oscillator
+on the board.
+
+Connections and IOs
+===================
+
+The DA14695 Development Kit USB has one LED and one push button which can be used
+by applications. The UART is connected to on-board serial converter and accessible
+via USB1 port on motherboard.
+
+The pin connections are as follows:
+
+* LED (red), = P1.01
+* BUTTON, labeled k1 = P0.06
+* UART RX, connected to J-Link serial = P0.08
+* UART TX, connected to J-Link serial = P0.09
+
+Programming and Debugging
+*************************
+
+Applications for the ``da14695_dk_usb`` board configuration can be
+built, flashed, and debugged in the usual way. See
+:ref:`build_an_application` and :ref:`application_run` for more details on
+building and running.
+
+Flashing
+========
+
+The DA14695 boots from an external flash connected to QSPI interface. The image
+written to flash has to have proper header prepended. The process is simplified
+by using dedicated `eZFlashCLI`_ tool that takes care of writing header and can
+handle different types of flash chips connected to DA1469x MCU. Follow instructions
+on `ezFlashCLI`_ to install the tool. Once installed, flashing can be done in the
+usual way.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/basic/blinky
+   :board: da14695_dk_usb
+   :goals: build flash
+
+Debugging
+=========
+
+The DA14695 Development Kit USB includes a `J-Link`_ adaptor built-in
+which provides both debugging interface and serial port.
+Application can be debugged in the usual way once DA14695 Development Kit USB
+is connected to PC via USB.
