Optimized for IoT applications: ultra-small form factor which even includes integrated antenna, the latest Bluetooth LE capabilities, and robust security.

Thalwil, Switzerland - April 10, 2025 - u-blox (SIX:UBXN), a global leader in positioning and short-range communication technologies for automotive, industrial and consumer markets, announces the launch of the ANNA-B5 Bluetooth® LE module. Built on Nordic Semiconductor's next-generation wireless SoC, the nRF54L15 chipset with industry-leading processing power and efficiency, this ultra-compact module (6.5 × 6.5 mm) features a fully integrated antenna on the module, high security, a powerful MCU as well as distance measurements capabilities. Packaged in the popular ANNA form factor from u blox, and globally certified, ANNA-B5 is setting a new standard for wireless MCU solutions in IoT applications.

Enhancing IoT connectivity and security

Designed with a new antenna solution for size-constrained, battery-powered applications, the ANNA-B5 delivers robust performance across industrial automation, smart home/smart building, healthcare, asset tracking and a broad range of other segments. Supporting Bluetooth® LE, 802.15.4 with Thread, Zigbee®, and Matter, ANNA-B5 ensures seamless connectivity. Qualified against Bluetooth® Core 6.0, the System in Package (SiP) module includes Bluetooth® Channel Sounding, providing more accurate range measurements.

With its next-generation security features, including physical tamper detection, secure boot, secure storage, and a crypto accelerator, it is designed to meet PSA Certified Level 3. This makes it an ideal choice for applications that require advanced security and compliance with the latest regulatory requirements, ensuring long-term viability in the evolving IoT landscape.

High performance in a ultra-small design

The ANNA-B5 module is powered by the Nordic Semiconductor nRF54L15 ultra-low power wireless SoC, featuring an Arm® Cortex®-M33 MCU running at 128 MHz, 256 kB of RAM, and 1.5 MB of non-volatile memory. Optimized for ultra-low power consumption, it is ideal for applications demanding extended battery life.

The module's compact size (6.5 × 6.5 × 1.2 mm) with a fully integrated antenna makes it suitable for a wide range of IoT devices. Its compatibility with other u-blox ANNA modules is key to effortless technology migration, such as transitioning to the latest generation of Bluetooth LE modules.

With its professional-grade u-connectXpress software, ANNA-B5 ensures reduced compliance costs, faster time to market, and seamless international deployment.

"u-blox did it again! We are thrilled to see the nRF54L Series - our next generation of low power wireless SoCs - encapsulated in such a small form factor as ANNA. Delivering the promise of the nRF54L15 SoC's unparalleled performance and capability, ANNA-B5 really pushes the limits to the maximum, meeting demands and needs of a huge variety of IoT applications." said Thomas Holmberg, Regional Sales Director at Nordic Semiconductor.

Availability

ANNA-B5 will be available for early sampling from summer 2025.
