# NRF52 DK
This is a sample self-contained ZMK board that is built for the ubiquitous NRF52 DK from Nordic. This can help jumpstart new board projects for people by showcasing various features on a known standard
You should be able to use this by plugging in an NRF52 DK, turning on the power switch, then running the following from the zmk/app folder:
````
west build --pristine -b nrf52dk_nrf52832 && west flash
````
## Features
- BLE functionality
- Simple keymap with modifiers
- Direct GPIO kscan
- Additonal custom code alongside ZMK runtime
- Connection LED
## Other details
Many of the files are from zmk/zepjhyr/boards/arm/nrf52dk_nrf52832, with additional modifications for ZMK.

Programming and Debugging
*************************
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
$ minicom -D <tty_device> -b 115200
Replace :code:`<tty_device>` with the port where the board nRF52 DK
can be found. For example, under Linux, :code:`/dev/ttyACM0`.
Then build and flash the application in the usual way.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: nrf52dk_nrf52832
: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 in the nRF52 DK
********************************************
There are 2 samples that allow you to test that the buttons (switches) and LEDs on
the board are working properly with Zephyr:
.. code-block:: console
samples/basic/blinky
samples/basic/button
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/nrf52dk_nrf52832/nrf52dk_nrf52832.dts`.
