# Sample Applications

We have provided various Conexio Stratus application examples and associated files to get started with creating and building your first application. The current sample applications are compatible with nRF Connect SDK (NCS) > v2.7.x and can be found in our [<mark style="color:red;">Github repository</mark>](https://github.com/Conexiotechnologies/conexio-stratus-firmware/tree/main/samples).

We provide samples and application examples that specifically target the Conexio Stratus Kit and demonstrate how to implement typical use cases with NRF Connect SDK  libraries and drivers.
