New variants in the u-blox Nora-B2 Bluetooth LE 6.0 module family integrate Nordic Semiconductor’s entire nRF54L series of ultra-low power wireless SoCs. Offering a choice of antennas and chipsets, these modules consume up to 50% less current than previous-generation devices while doubling processing capacity.
The NORA-B2 series comprises four variants that differ in memory size, design architecture, and price level. Each variant comes with either an antenna pin or embedded antenna.
- NORA-B20 features an nRF54L15 SoC and integrates a 128-MHz Arm Cortex-M33 processor, a RISC-V coprocessor, and an ultra-low power multiprotocol 2.4-GHz radio. It comes with 1.5 MB of NVM and 256 KB RAM.
- NORA-B21, based on an nRF54L10 SoC, is designed for mid-range applications. It has 1.0 MB of NVM and 192 KB of RAM and handles multiple wireless protocols simultaneously, including Bluetooth LE, Bluetooth Mesh, Thread, Matter, Zigbee, and Amazon Sidewalk.
- NORA-B22 employs an nRF54L05 SoC. It is intended for cost-sensitive applications but still provides access to up to 31 GPIOs. It includes 0.5 MB of NVM and 96 KB of RAM.
- NORA-B26, based on an nRF54L10, is designed for customers using the network coprocessor architecture. It comes pre-flashed with the u-blox u-connectXpress software, allowing customers to easily integrate Bluetooth connectivity into their products with no prior knowledge of Bluetooth LE or wireless security.
All NORA-B2 modules are designed for PSA Certified Level 3 security and meet the Bluetooth Core 6.0 specification, including channel sounding for accurate ranging. They also carry global certification, enabling manufacturers to launch products worldwide with minimal effort.
NORA-B20 samples are available now, while NORA-B21 and B22 are in limited evaluation. A pre-release of u-connectXpress for NORA-B26 is available for early adopters.
