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.
