B204 USB dongle

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

The PCB has been created to match the size of a USB connector, thus providing minimum amount of components and no need for external cables. The B204 board is designed to use the NINA-B1 module with the preflashed u-blox connectivity software. The u-blox connectivity software enables the use of the Bluetooth Low Energy functions, controlled by AT-commands over the USB interface.
