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.

Documentation for different versions of the nRF Connect SDK is available at the following links:
