u-blox introduced six new variants of the NORA-B2 Bluetooth Low Energy module family of devices, integrating Nordic Semiconductor’s next-level nRF54L Series of ultra-low-power wireless SoCs. The NORA-B2 family offers a versatile solution for mass-market segments, enabling the choice of antennas, architectures, and chipsets.
The devices maintain ultra-low power consumption and high processing efficiency, consuming less current than previous-generation devices while doubling process capacity. Security features target a wide range of IoT applications, such as smart-home devices, industrial automation, and healthcare.
The NORA-B20 integrates a 128-MHz Arm Cortex-M33 processor, a RISC-V co-processor, and an ultra-low-power multiprotocol 2.4-GHz radio, with 1.5 MB of non-volatile memory and 256-kB RAM. The NORA-B21 is designed for mid-range applications, with 1.0 MB of non-volatile memory and 192 kB of RAM. It can handle multiple wireless protocols simultaneously, including Bluetooth LE, Bluetooth Mesh, Thread, Matter, Zigbee, and Amazon Sidewalk.
The NORA-B22 suits cost-sensitive applications while providing access to up to 31 GPIOs with 0.5 MB of non-volatile memory and 96 kB of RAM. The NORA-B26 serves customers using the Network Co-Processor architecture and comes pre-flashed with u-blox u-connectXpress software, which integrates Bluetooth connectivity into products with no prior knowledge of Bluetooth LE or wireless security.
Designed for PSA Certified Level 3 security, NORA-B2 modules include secure boot and updates, tamper detection, and secure firmware over-the-air updates. They're also qualified for Bluetooth Core 6.0, which includes channel sounding for tracking and location applications. NORA-B2 variants offer an antenna pin for connecting an external antenna of choice or come with a PCB antenna. All module versions come with global certification.
