u-blox's NINA-B1 series modules are small stand-alone Bluetooth Low Energy (BLE) modules featuring Bluetooth v4.2 (software upgradeable to v5), 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 BLE 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 to add their application to run on the built-in 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 BLE stack using SDK from Nordic Semiconductor or ARM mbed™. 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.
