Other hardware features are not yet supported in this Zephyr port.
The default configuration can be found in the defconfig file:
:zephyr_file:`boards/st/nucleo_g0b1re/nucleo_g0b1re_defconfig`
Connections and IOs
===================
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
input (with or without pull-up or pull-down), or as peripheral alternate function. Most of the
GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current
capable except for analog inputs.

----------------------------------
- UART_1 TX/RX : PC4/PC5
- UART_2 TX/RX : PA2/PA3 (ST-Link Virtual Port Com)
- I2C1 SCL/SDA : PB8/PB9 (Arduino I2C)
- I2C2 SCL/SDA : PA11/PA12
- SPI1 NSS/SCK/MISO/MOSI : PB0/PA5/PA6/PA7 (Arduino SPI)
- SPI2 NSS/SCK/MISO/MOSI : PB12/PB13/PB14/PB15

Programming and Debugging
*************************
Nucleo G0B1RE board includes an ST-LINK/V2-1 embedded debug tool interface.
Applications for the ``nucleo_g0b1re`` board configuration can be built and
flashed in the usual way (see :ref:`build_an_application` and
:ref:`application_run` for more details).
Flashing
========
The board is configured to be flashed using west `STM32CubeProgrammer`_ runner,
so its :ref:`installation <stm32cubeprog-flash-host-tools>` is required.
Alternatively, OpenOCD, JLink, or pyOCD can also be used to flash the board using
the ``--runner`` (or ``-r``) option:
.. code-block:: console
$ west flash --runner openocd
$ west flash --runner jlink
$ west flash --runner pyocd
For STM32G0 support pyocd needs additional target information,
which can be installed by adding "pack" support with the following pyocd command:
.. code-block:: console
$ pyocd pack --update
$ pyocd pack --install stm32g0
Flashing an application to Nucleo G0B1RE
----------------------------------------
Here is an example for the :zephyr:code-sample:`blinky` application.
.. zephyr-app-commands::
:zephyr-app: samples/basic/blinky
:board: nucleo_g0b1re
:goals: build flash
You will see the LED blinking every second.
Debugging
=========
You can debug an application in the usual way. Here is an example for the
:zephyr:code-sample:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: nucleo_g0b1re
:maybe-skip-config:
:goals: debug
