NORA-B2 series - Data sheet 1.6 Software The Open CPU architecture of NORA-B2 series modules allows integrators to develop and run their own applications on the built-in Arm® Cortex®-M33 core. u-blox recommends the Nordic Semiconductor nRF Connect SDK [5] for development. The nRF Connect SDK integrates the Zephyr Real-Time Operating System (RTOS), MCUboot secure bootloader, and Nordic Semiconductor’s nrfxlib device drivers for the nRF54Lxx and peripherals. Functional description

NORA-B2 series - Data sheet 2 Interfaces NORA-B2 supports a wide range of connectivity options, including a 2.4 GHz radio with an antenna connection, digital and analog I/O, and debug capabilities. The module provides full access to all GPIOs and peripheral interfaces available on the embedded nRF54Lxx, ensuring seamless integration into customer applications. For more information regarding function and use, see also the nRF54Lxx datasheet [4]. 2.1 Peripherals power domains NORA-B2 features multiple Power Domains (PD) for low-power operation, including fast MCU and lower speed domains. Figure...

NORA-B2 series - Data sheet 2.1.1 Fast MCU domain The fast MCU domain powers the Arm Cortex-M33 processor and its supporting debug system, which enables debugging and Embedded Trace Macrocell (ETM) tracing. The CPU executes program code from RRAM through an instruction cache. Data is stored in single-cycle RAMs, which are divided into multiple bus subordinates but form a continuous RAM space in the memory map. The fast domain also contains high-speed peripherals. Lower speed domains NORA-B2 are three lower speed power domains: • Radio domain – contains the short-range radio as well as supporting...

NORA-B2 series - Data sheet • External source – An externally generated 32.768 kHz clock source applied to XL1, and XL2 pins. The accuracy of the clock is dependent on the external source. • Synthesized clock (LFSYNT) – 32.768 kHz clock generated from the HFCLK, which assumes the accuracy is ±20 ppm. LFSYNT requires HFCLK to run, which results in higher-than-average power consumption. 2.4 RF antenna interfaces 2.4.1 2.4 GHz radio (ANT) NORA-B2 model versions support two 2.4 GHz antenna solutions: • NORA-B2x1 modules include an antenna pin (ANT). The pin has nominal characteristic impedance of...

NORA-B2 series - Data sheet The three main power modes are: • System ONDLEsub-modes • System OFF- lowest power consumption Depending on the application, the module should spend most of its time in either System ON IDLE or System OFF mode to minimize current consumption. System ON is the default operation after power-on reset. You can switch on or reboot the NORA-B2 modules in one of the following ways: • Rising edge on the VCC pin to a valid supply voltage • Issuing a reset of the module. See also Module reset. An event to wake up from the System OFFmode to the active mode can be triggered by:...
