IIoT Made Easy: Smallest Bluetooth 5 Module Unveiled!


Supporting a wide range of Industrial Internet of Things (IIoT) applications that require high-speed Bluetooth connectivity and space-constrained designs, u-blox has launched a new Bluetooth 5 module, ANNA-B1.

Typical applications for the ANNA‑B1 Bluetooth module are small devices such as power tools, industrial and medical sensor products, wearables, and point of sale devices that require Bluetooth 5 connectivity, either individually or as part of a mesh network. Medical and sports wearables and telematics aftermarket products including insurance boxes will benefit from the ANNA‑B1’s small footprint.

Key features of the new module include a compact size and an industrial operating temperature range. It is packed as a System-in-Package (SiP) design into a tiny 6.5 x 6.5 x 1.2 mm size. It is a miniaturized variant of the u‑blox NINA‑B1 Bluetooth low energy module.

The module features an Arm Cortex-M4 microcontroller unit with a floating point unit, flash and RAM. The open CPU option provides full access to the module’s microcontroller so that custom applications can be embedded into the module.

Developers can also leverage the module’s pre-flashed u‑blox connectivity software to speed up time to market. The software is tested and verified and supports many IoT applications.

The software includes a GATT client and server for connectivity attributes, Serial Port Service, simultaneous peripheral and central role, and NFC technology for easy pairing to other Bluetooth low energy devices.

ANNA-B1 has a built-in antenna, but also allows for external antenna designs.

Comments Len Albertsson, Principal Product Manager, Product Strategy Short Range Radio at u‑blox. “In an industry where reductions in size and weight often come at the expense of product features, we’re very excited by how well our new ANNA-B1 module ranks alongside the NINA-B1 module.”

Engineering samples of the ANNA‑B1 will be available in Q2 2018.
