NINA-B2 Series - Standalone dual mode Bluetooth modules

Secure industrial dual mode Bluetooth made easy

The NINA-B2 series are small, dual-mode Bluetooth standalone modules designed for ease-of-use and integration in professional applications. The modules are delivered with u-blox connectivity software that provides support for both peripheral and central roles, Serial Port Profile, GATT client and server, beacons, u-blox Bluetooth low energy Serial Port Service - all configurable from a host using AT commands.

NINA-B2 provides top grade security, thanks to secure boot, which ensures the module only boots up with original u-blox software. Intended applications include industrial automation, wireless-connected and configurable equipment, point-of-sales, and health devices.

NINA-B222 comes with an internal antenna while NINA-B221 has a pin for use with an external antenna. The internal PIFA antenna is specifically designed for the small NINA form factor and provides an extensive range, independent of ground plane and component placement.

The NINA-B2 series is globally certified for use with the internal antenna or a range of external antennas. This greatly reduces time, cost and effort for customers integrating NINA-B2 in their designs.
