Overview
The nRF51 Dongle (PCA10031) hardware provides support for the Nordic Semiconductor nRF51822 ARM Cortex-M0 CPU.
More information about the board can be found at the
nRF51 Dongle website. The Nordic Semiconductor TechDocs
contains the processor's information and the datasheet.
Hardware
nRF51 Dongle has two external oscillators. The frequency of the slow clock is 32.768 kHz. The frequency of the main clock is 16 MHz.

See nRF51 Dongle website_ and Nordic Semiconductor TechDocs_
for a complete list of nRF51 Dongle hardware features.
Programming and Debugging
.. zephyr:board-supported-runners::
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 :zephyr:code-sample: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 nRF51 Dongle
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: nrf51dongle/nrf51822 :goals: build flash
Refer to the :ref:nordic_segger page to learn about debugging Nordic boards with a
Segger IC.
Testing the LEDs on the nRF51 Dongle
Build and flash the :zephyr:code-sample:blinky sample to test that the onboard LED
is working properly with Zephyr.
