Overview
The NORA-B1 series of small stand-alone, open CPU module types support Bluetooth 5.2 device
connectivity and operate in temperatures of up to 105 °C. The modules are built on the Nordic
nRF5340 System on a Chip as an open CPU solution, where customer applications run on two Arm®
Cortex®-M33 processor cores with integrated flash and RAM memory.
The application core implements TrustZone® technology that includes an Arm Cortex-M33
processor, Digital Signal Processing (DSP) extension, Floating-point Unit (FPU), and CryptoCell™-312
with roots-of-trust and other security mechanisms for IoT and high-performance applications. The
processor is clocked at either 128 or 64 Mhz.
The network core includes an Arm® Cortex®-M33 processor with integrated 2.4 GHz radio capable of
handling Bluetooth Low Energy (LE), 802.15.4 for Thread and Zigbee, and Nordic proprietary
protocols. The processor is clocked at 64 Mhz.
With features like Direction finding (Angle-of-Arrival and Angle-of-Departure), Bluetooth long range,
and Bluetooth Low Energy (LE) Audio, NORA-B1 series modules support Bluetooth LE services such
as serial port communication, GATT, beacons, and mesh along with a range of wired interfaces,
including UART, QSPI, SPI, I2C, I2S, USB, QDEC, PDM, PWM, and ADC.
NORA-B1 series modules support multiple power supply configurations and several available
antenna options: U.FL connector (NORA B100), antenna pin (NORA-B101), and on-board PCB trace
antenna (NORA-B106).
