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.
