## What it is
Nordic Semiconductor's nRF Connect SDK, the main repository containing subsystems, libraries, samples, and applications for developing firmware on nRF SoCs. It serves as the west manifest repository integrating Zephyr RTOS and related components.

## Use cases
- build firmware for nRF52 and nRF53 Bluetooth SoCs
- develop cellular IoT applications on nRF91
- create low-power wireless sensor applications
- integrate BLE, Thread, Zigbee, or LTE-M/NB-IoT connectivity
- write Zephyr-based applications for Nordic hardware

## When to choose
- you are developing firmware for Nordic Semiconductor nRF chips
- you need a production-grade SDK with Bluetooth, cellular, or mesh support
- you want Zephyr RTOS with Nordic-specific libraries and samples

## When to avoid
- you target non-Nordic microcontrollers
- you need a bare-metal environment without an RTOS
- you want a lightweight SDK without the Zephyr build system

## Facets
- artifact type: framework
- maturity: active
- function: sdk, embedded, middleware
- domain: embedded-systems, iot, developer-tools
- platform: embedded, iot, c, cross-platform
- tags: nordic-semiconductor, nrf52, nrf53, nrf91, zephyr, west, ble, cellular-iot, firmware-development, bluetooth
