| 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`_. |

| |
| 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. |
| |
| .. note:: |
| Trusted Firmware-M (TF-M) and building the ``ns`` target is not supported for this board. |
| |
| 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.dtsi`. |
