# Nordic Semiconductor's nRF5 SDK for Thread
The [nRF5 Software Development Kit (SDK) for Thread][nRF5-SDK-Thread] helps you when developing Thread products with Nordic Semiconductor's advanced nRF52840 System on Chip (SoC).
The <i>nRF5 SDK for Thread</i> includes:
- a pre-built OpenThread stack for the Nordic nRF52840 SoC with ARM® CryptoCell-310 support,
- unique support for DFU-over-Thread (Device Firmware Upgrade),
- examples to demonstrate interactions between nodes performing different Thread roles with the use of OpenThread and built-in CoAP protocol,
- support for an OpenThread Network Co-Processor (NCP),
- Border Router and cloud connectivity example,
- Thread native commissioning with NFC example,
- range of PC tools including a Thread Topology Monitor,
- software modules inherited from the nRF5 SDK e.g. peripheral drivers, NFC libraries etc.
#### Important notice
Due to legal restrictions support for hardware-accelerated cryptography utilizing ARM CryptoCell-310 is only available in mbedTLS library (libmbedcrypto.a) provided with the <i>nRF5 SDK for Thread</i>. The library available in OpenThread repository does not support hardware acceleration. You can still use it, but the commissioning procedure takes much more time in such case. For the best performance and user experience, use the library provided with the SDK.
