NINA B1 Bluetooth low energy module

Fully certified Bluetooth low energy module with Arm® Cortex®-M4 with FPU and NFC /media/uploads/lenalbertsson/nina-b1-angle_small.png


The NINA-B1 stand-alone Bluetooth low energy module is a compact module with very low power consumption and is suitable for applications using coin cell batteries. The module is built on the Nordic nRF52832 SoC with Bluetooth low energy v5.0 radio, Arm® Cortex®-M4 with FPU processor and NFC tag. With the use of the Arm Mbed IDE a customer developed application and/or Bluetooth services/attributes can be embedded on top of the integrated software stack and tools.

The NINA-B1 is a stand-alone product with no additional hardware required. Additional sensors such as temperature sensor, accelerometers, LEDs etc., can be connected directly to the module. The module is offered in professional grade for applications such as health care, asset tracking, connected cities, home automation, smart energy, manufacturing and telematics.

The NINA-B1 modules are fully Bluetooth qualified and provide global modular approval. They are also compliant with safety and medical standards.
