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.
To access different versions of the nRF Connect SDK documentation, use the version drop-down in the top right corner. A “99” at the end of the version number of this documentation indicates continuous updates on the main branch since the previous major.minor release.
