NINA-B1 Series - Stand-alone Bluetooth Low Energy (v4.2) modules (Bluetooth 5 Ready)

Compact stand-alone Bluetooth Low Energy (v4.2) modules (Bluetooth 5 Ready)

u-blox NINA-B1 modules are small, stand-alone Bluetooth low energy modules featuring Bluetooth v4.2 (software upgradeable to Bluetooth 5), a powerful ARM® Cortex®-M4 with FPU, and state-of-the-art power performance. The embedded low power crystal improves the power consumption by enabling optimal power save modes.

The NINA-B1 is delivered with u-blox connectivity software that provides support for u-blox Bluetooth low energy Serial Port Service, GATT client and server, beacons, and simultaneous peripheral and central roles - all configurable from a host using AT commands.

NINA-B1 offers full flexibility for customers who prefer their application to run on the built-in ARM Cortex-M4 with FPU. With 512 kB flash and 64 kB RAM, it offers the best-in-class capacity for customer applications running on top of the Bluetooth low energy stack using SDK from Nordic Semiconductor or ARM mbed. Additionally, NFC and interfaces such as SPI, I²C, and I2 S are available. In combination with Wirepas Connectivity stack, NINA-B1 can form large scale industrial mesh networks for several applications such as lighting, asset tracking, and metering.

NINA-B112 comes with an internal antenna and NINA-B111 has a pin for use with an external antenna. The internal PIFA antenna is specifically designed for the small NINA-B1 form factor and provides an extensive range of more than 300 m, independent of ground plane and component placement.
