u-blox NINA-B50 series- Stand-alone Bluetooth 5.3 low energy modules

NINA-B50 series are small Bluetooth Low Energy 5.3 triple-core wireless MCU modules, qualified in Automotive or Professional grade. The main core is a powerful Arm Cortex-M33 allowing implementation of advanced applications with the MCUXpresso SDK. A wide range of interfaces (including 16-bit ADC) offer flexibility. Automotive NINA-B50 modules support FlexCAN and LIN bus, for seamless integration in automotive or industrial bus networks, for a lightweight alternative to traditional cables.

The dedicated radio core, with its own flash and RAM, frees up resources for the main application and provides optimized current consumption. This can be used to improve system level power consumption, letting other systems sleep when not in use, such as cellular or full systems in keyless entry systems. In addition to upgradeable Bluetooth low energy 5.3, the NINA-B50 professional grade modules also support Matter, Thread, and Zigbee. This allows interoperability in the growing Matter ecosystem, and the dual-PAN feature allows bridging use cases for Thread and Zigbee with fast and reliable time-slicing.

The third core is the isolated EdgeLock secure enclave, with advanced security features including secure boot, debug, over-the-air updates, root-of-trust, hardware cryptography, on-the-go flash encryption, and Arm TrustZone secure execution environment. NINA-B5 also supports the NXP EdgeLock2GO service for installing keys and certificates into the end device; it is authorized for Matter device attestation certificates, making it easier to deploy Matter devices.

The NINA-B506 comes with an internal PCB antenna providing high performance and an extensive range, while NINA-B501 has a module pin for an external antenna. NINA-B50 is globally certified, reducing time, cost and effort for customers. Example applications include in-vehicle light control, keyless entry, access control, battery management, telematics, smart buildings and homes, and industrial automation.
