u-blox NORA-B2 Bluetooth LE module series

u-blox has introduced several new variants of its NORA-B2 Bluetooth Low Energy modules, integrating the entire range of Nordic Semiconductor’s next-level nRF54L series of ultralow-power wireless systems-on-chip.

The wireless modules combine ultralow power consumption and high processing efficiency, consuming up to 50% less current than previous-generation devices while doubling process capacity. The series comprises four variants that differ in memory sizes, design architectures and price levels to match almost any device manufacturer’s requirements.

NORA-B20 uses ultralow-power nRF54L15 SoC and integrates a 128 MHz Arm Cortex-M33 processor, a RISC-V co-processor and an ultralow-power multiprotocol 2.4 GHz radio. It comes with 1.5 MB of non-volatile memory (NVM) and 256 KB RAM.

NORA-B21, based on ultralow-power nRF54L10 SoC, is designed for mid-range applications. It has 1 MB of NVM and 192 KB of RAM and can handle multiple wireless protocols simultaneously, including Bluetooth LE, Bluetooth Mesh, Thread, Matter, Zigbee and Amazon Sidewalk.

NORA-B22 is designed for cost-sensitive applications but still provides access to up to 31 GPIOs. It offers 0.5 MB of NVM and 96 KB of RAM.

NORA-B26 is designed for those using Network Co-Processor architecture and comes pre-flashed with the u-blox u-connectXpress software, allowing users to easily integrate Bluetooth connectivity into their products with no prior knowledge of Bluetooth LE or wireless security.

The modules are designed for PSA Certified Level 3 security, incorporating features such as secure boot and updates, tamper detection, and secure firmware over-the-air (FOTA) updates. These security measures keep IoT devices protected against any potential threats, safeguarding both data and functionality; this makes the modules suitable for IoT applications such as smart home devices, industrial automation or health care. The modules are also qualified against Bluetooth Core 6.0 that includes Channel Sounding, enabling tracking and locating use cases.

The variants either come with an antenna pin for connecting an external antenna of choice or are designed with a patented PCB antenna providing high RF performance. All versions come with global certification allowing device manufacturers to launch their products worldwide with minimal effort.
