Support – Nordic Semiconductor DevZone development forum

For support with questions about the development of software using the nRF Connect SDK, refer to
the Nordic Semiconductor DevZone support site [19]. Public discussions and private tickets are
available on the site, where the Nordic engineers and forum members respond to all contributions.

2.1.4

Example code

The EVK-NORA-B10x evaluation kits are compatible with most nRF Connect SDK projects that
support the nRF5340 DK without any changes required. See the EVK-NORA-B1 user guide [3] for
information about installing and using the development tools.
