Applications
The nRF Connect SDK provides a set of example applications that show how to implement typical user scenarios using Nordic Semiconductor devices. Applications typically include a fully integrated software stack and can serve as a starting point for developing your product. They use interface drivers and libraries from the nRF Connect SDK and its set of repositories to implement a specific use case, while Samples showcase a single feature or library.
Some applications target custom hardware designed for a specific use case. You can also run them on different hardware like a generic development kit, but with limited functionality.
If you want to list applications available for one or more specific boards, use the nRF Connect for Visual Studio Code extension to filter them.
