Requirements

This shield can only be used with a board which provides a configuration for Arduino connectors and defines node aliases for SPI and GPIO interfaces (see :ref:`shields` for more details).

Programming

Set --shield semtech_sx1272mb2das when you invoke west build. For example:

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/lorawan/class_a
   :board: nucleo_f429zi
   :shield: semtech_sx1272mb2das
   :goals: build
