Both modules are based on the latest generation nRF54 Series Systems-on-Chip (SoCs) from Nordic Semiconductor and support Bluetooth LE 5.4 and Thread/Matter technologies in a compact, power-efficient, and secure format.
The ALMA-B1 and NORA-B2 modules are designed for a wide range of IoT applications, including industrial automation, healthcare, and smart home. ALMA-B1 is a high-end wireless MCU, while NORA-B2 brings ultra-low power to less complex applications. In the indoor positioning example, ALMA-B1 could act as an anchor point due to its vast processing capabilities, while the power efficiency of NORA-B2 makes it suitable for asset tracking tags.
Powered by the nRF54H20 and the nRF54L15 Nordic low-power multiprotocol SoCs, both modules provide IoT devices with the processing power for edge computing and machine learning without additional components. With more than twice the processing power of previous Bluetooth LE modules, the ALMA-B1 can even replace general-purpose MCUs in a compact solution.
Both modules also offer a significant reduction in power consumption. NORA-B2 consumes up to 50% less current compared to previous generations of Bluetooth LE modules meaning smaller batteries or longer battery life in end products.
Designed for PSA Certified Level 3, ALMA-B1 and NORA-B2 provide the highest levels of IoT security. In addition to features like secure boot, secure storage, secure debug interfaces, and hardware crypto accelerators, both modules include next-generation security features like physical tamper detection and protection against side-channel attacks.
The sizes of the modules (10 x 11 mm or 10 x 14 mm) save considerable space and facilitate migration from other u-blox’s modules. Both modules come with global certifications.
ALMA-B1 and NORA-B2 are available as wireless MCUs. Both modules offer two antenna options: an antenna pin or an embedded PCB antenna.
Samples for both modules will be available in Q3 2024.
