* CLOCK
* FLASH
* :abbr:`GPIO (General Purpose Input Output)`
* :abbr:`I2C (Inter-Integrated Circuit)`
* :abbr:`MPU (Memory Protection Unit)`
* :abbr:`NVIC (Nested Vectored Interrupt Controller)`

.. note::
The BMD-300-EVAL, BMD-301-EVAL, and BMD-350-EVAL share the same
pin headers and assignments. The boards are different only in
the module used on the board. The BMD-300 and BMD-301 modules
share the same footprint and differ only in the antenna. The
BMD-350 module utilizes the nRF52832 CIAA WLCSP package.
More information about the BMD-300-EVAL, BMD-301-EVAL, and
BMD-350-EVAL and the respective modules can be found at the
`u-blox website`_. All of the Nordic Semiconductor examples for
the nRF52 DK (nrf52dk_nrf52832) may be used without modification.
Hardware
********
The BMD-300/301/350 module on the board contains an internal
high-frequency oscillator at 32MHz. There is also a low frequency
(slow) oscillator of 32.768kHz. The module itself does not include
the slow crystal; however, the EVAL boards do.
.. note::
When targeting a custom design without a slow crystal,
be sure to modify code to utilize the internal RC
oscillator for the slow clock.

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
BMD-300/301/350-EVAL 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: ubx_bmd300eval_nrf52832
:goals: build flash
Debugging
=========
Refer to the :ref:`nordic_segger` page to learn about debugging
u-blox boards with a Segger J-LINK-OB IC.
Testing the LEDs and buttons in the BMD-330-EVAL
************************************************
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/ubx_bmd300eval_nrf52832/ubx_bmd300eval_nrf52832.dts`.
