B204: Bluetooth Low Engery and 5.0 USB Dongle - NINA-B1

B204 is a simple USB dongle that uses the u-blox NINA-B1 series module. The blueprint B204 provides a reference for integrating the NINA-B1 Bluetooth® Low Energy (BLE) module as a USB dongle.

The PCB has been created to match the size of a USB connector, thus providing the minimum number of components and without any external cables. This application note provides information about the hardware solutions implemented in B204.

The NINA-B1 series modules are small, stand-alone Bluetooth low energy modules featuring Bluetooth 5, a powerful Arm® Cortex®-M4 with FPU, and state-of-the-art power performance. The embedded low power crystal in NINA-B1 minimizes power consumption, thus extending the battery life.

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