Nordic Semiconductor supports OpenThread with their nRF5x family of SoCs and actively contributes to the ongoing development of OpenThread.

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 nRF5 SDK for Thread. The library available in the OpenThread repository does not support hardware acceleration. You can still use it, but the commissioning procedure takes much more time in such cases. For the best performance and user experience, use the library provided with the SDK.



The nRF52811 is a Bluetooth 5.1 Direction Finding SoC with comprehensive protocol support. It is the 4th addition to the nRF52 Series platform, extending the numerous applications and use cases already covered by the platform.

The nRF52811 SoC is capable of the latest and greatest features of Bluetooth 5.1, the most prominent being Direction Finding, taking Bluetooth positioning to new heights.

It is built around a 64 MHz Arm® Cortex™-M4 CPU, and has a range of digital peripherals and interfaces such as PDM, PWM, UART, SPI and TWI. It also has a capable 12-bit ADC. Exceptionally low energy consumption is achieved using a sophisticated on-chip adaptive power management system.

The radio in the nRF52811 SoC has comprehensive protocol capabilities, including Bluetooth 5.1 Directing Finding, all Bluetooth 5 features, 802.15.4, Thread, Zigbee, ANT and 2.4 GHz proprietary. It has 4 dBm TX power and has been optimized to offer the best RX sensitivity of all SoCs in the nRF52 Series.
