Welcome to the nRF Connect SDK!¶
The nRF Connect SDK is where you begin building low power wireless applications with Nordic Semiconductor nRF52, nRF53, and nRF91 Series devices.
The SDK contains optimized cellular IoT (LTE-M and NB-IoT), Bluetooth Low Energy, Thread, Zigbee, and Bluetooth mesh stacks, a range of applications, samples, and reference implementations, as well as a full suite of drivers for Nordic Semiconductor’s devices. The nRF Connect SDK includes the Zephyr™ real-time operating system (RTOS), which is built for connected low power products.
Note
nRF53 Series devices are supported for production. Wireless protocol stacks and libraries may indicate support for development or support for production for different series of devices based on verification and certification status.
To access different versions of the nRF Connect SDK documentation, use the version drop-down in the top left corner. To view the documentation from the different repositories that are part of nRF Connect SDK, click the arrow in the bottom left corner and select the desired document set. A “99” at the end of the version number of this documentation indicates continuous updates on the master branch since the previous major.minor release.
The search functionality only works for the documentation set you are in. For example, if you search in the nRF Connect SDK documentation set, you will only find documents related to it, not Zephyr documentation.
