High performance Bluetooth module for advanced applications
The Bluetooth 5.2 module hosts an Arm® Cortex® M33 dual core MCU and brings advanced security functionality to short range radio applications.

Swiss company, u-blox has announced the NORA-B1 Bluetooth module, the latest member of its short range radio portfolio. Based on Nordic Semiconductor’s latest nRF5340 Bluetooth low energy chipset – the first to host a powerful Arm® Cortex® M33 dual core MCU – NORA-B1 is designed to meet the needs of performance-oriented applications in areas such as industrial, medical, and smart building and smart city markets.

NORA-B1 helps engineers get maximum value out of a single component. Taking advantage of the chipset’s dual core MCU, NORA-B1 can handle performance-oriented applications and even drive a display without requiring an external host processer. With one low-power-optimized core dedicated to managing network connectivity and a second high performance core exclusively running the device application, NORA-B1 enables smooth and uninterrupted operation with minimal processing latency.

The Arm® TrustZone® offers enhanced security, enabling a trusted execution environment by fully separating secure and non-secure Flash, RAM, peripherals, and GPIOs. The module also comes with the state-of-the-art Arm CryptoCell-312, which provides hardware-accelerated cryptography and, in combination with the key management unit (KMU), enables a root of trust and secure key storage.

“Nordic Semiconductor’s nRF5340 chipset brings Bluetooth-enabled connectivity to a new, more demanding class of applications, not only in terms of computing power but also in terms of security,” says Pelle Svensson, Senior Product Marketing Manager, Short Range Radio, at u-blox.

Compact, extensively qualified, and globally certified, NORA-B1 brings the full promise of Bluetooth 5.2 to wireless applications, while also supporting ZigBee and Thread. LE audio, which can concurrently stream multiple channels with lower power consumption than existing technology, brings a major upgrade to audio data transmission, one of Bluetooth’s most popular use cases.
