+
+Overview
+********
+
+The nRF9160 Thing Plus designed by Circuit Dojo is a single-board development
+for bringing your LTE-M and NB-IoT applications to life. The sparkfun_thing_plus_nrf9160
+board configuration leverages the pre-existing support for the Nordic Semiconductor
+nRF9160. Supported nRF9160 peripherals include:
+
+* :abbr:`ADC (Analog to Digital Converter)`
+* CLOCK
+* FLASH
+* :abbr:`GPIO (General Purpose Input Output)`
+* :abbr:`I2C (Inter-Integrated Circuit)`
+* :abbr:`MPU (Memory Protection Unit)`
+* :abbr:`NVIC (Nested Vectored Interrupt Controller)`
+* :abbr:`PWM (Pulse Width Modulation)`
+* :abbr:`RTC (nRF RTC System Clock)`
+* Segger RTT (RTT Console)
+* :abbr:`SPI (Serial Peripheral Interface)`
+* :abbr:`UARTE (Universal asynchronous receiver-transmitter with EasyDMA)`
+* :abbr:`WDT (Watchdog Timer)`
+* :abbr:`IDAU (Implementation Defined Attribution Unit)`
+
+More information about the board can be found at the
+`nRF9160 Thing Plus Documentation`_.
+
+
+Hardware
+********
+
+Connections and IOs
+===================
+
+The nRF9160 Thing Plus has everything you know and love about
+the Feather platform. Here are some of the highlights:
+
+LED
+---
+
+* D7 (blue) = P0.03
+
+Push buttons and Switches
+-------------------------
+
+* MODE = P0.12
+* RESET
+
+USB
+---
+
+Contains a USB/UART connection for both debugging and loading new
+code using a UART Enabled MCUBoot.
+
+Standard Battery Connection
+----------------------------
+
+The nRF9160 Thing Plus has a 2 pin battery connector on board. Lithium Polymer batteries >
+300mA required.
+
+Nano SIM Holder
+---------------
+
+The nRF9160 Thing Plus has a built-in nano SIM (4FF) holder located
+on the bottom side.
+
+
+Programming and Debugging
+*************************
+
+sparkfun_thing_plus_nrf9160 can be used with most programmers like:
+
+* J-Link (the nRF53-DK is recommended)
+* CMSIS-DAP based programmers
+
+Check out `Getting Started`_ for more info.
+
+Building an application
+=======================
+
+In most cases you'll want to use the ``ns`` target with any of the Zephyr
+or Nordic based examples. Some of the examples do not use secure mode,
+so they do not required the ``ns`` suffix. A great example of this is the
+`hello_world` below:
+
+Flashing
+========
+
+Follow the instructions in the :ref:`nordic_segger` page to install
+and configure all the necessary software. Further information can be
+found in :ref:`nordic_segger_flashing`. Then build and flash
+applications as usual (see :ref:`build_an_application` and
+:ref:`application_run` for more details).
+
+Here is an example for the :ref:`hello_world` application.
+
+First, run your favorite terminal program to listen for output.
+
+.. code-block:: console
+
+   $ screen /dev/<tty_device> 115200
+
+Replace :code:`<tty_device>` with the port where the nRF9160 Thing Plus
+can be found. In most cases (On Linux/Mac) it will be: :code:`/dev/tty.SLAB_USBtoUART`.
+
+Then build and flash the application in the usual way.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: sparkfun_thing_plus_nrf9160
+   :goals: build flash
+
+Debugging
+=========
+
+Refer to the :ref:`nordic_segger` page to learn about debugging Nordic boards with a
+Segger IC.
+
+
+Testing the LEDs and buttons on the nRF9160 Thing Plus
+******************************************************
+
+There are 2 samples that allow you to test that the buttons (switches) and LEDs on
+the board are working properly with Zephyr:
+
+* :ref:`blinky-sample`
+* :ref:`button-sample`
+
+You can build and flash the examples to make sure Zephyr is running correctly on
+your board. The button and LED definitions can be found in
+:zephyr_file:`boards/arm/sparkfun_thing_plus_nrf9160/sparkfun_thing_plus_nrf9160_common.dts`.
