Bluetooth 5 module delivers power-efficient connectivity

14-03-2024 | Mouser Electronics | Semiconductors

Mouser now stocks the ANNA-B112 stand-alone Bluetooth 5 module from u-blox. The module provides efficient, high-performance connectivity in an ultra-compact package. The BLE module is ideal for power-sensitive applications, including IoT, asset tracking, lighting, and metering.

The module features Bluetooth 5 and an integrated Arm Cortex-M4 microprocessor with an FPU. The 6.5mm × 6.5mm × 1.2mm SiP allows for advanced Bluetooth capabilities in small devices without compromising performance or functionality. The module includes an integrated antenna providing a range of 160m and an antenna pin for the design-in of an external antenna. Operating within a supply voltage range of 1.7V to 3.6V DC and a temperature range from -40C to +85C, the module delivers reliable performance in various power and environmental conditions. The versatile module includes SPI, I2C, and I2S interfaces and support for NFC, Bluetooth Mesh, AirFuel, and Apple HomeKit.

The module includes u-connectXpress software for simplified development and accelerated time to market; it may also be used as an open CPU solution to run customer application firmware. The software supports u-blox BLE Serial Port Service, GATT client and server, beacons, NFC, Bluetooth mesh, and simultaneous peripheral and central roles, all configurable from a host via AT commands. With 512KB of flash memory and 64KB of RAM, the module delivers superior capacity for customer applications running on the BLE stack.

The module is supported by the EVK-ANNA-B112 evaluation kits, also available from Mouser. The evaluation kits are offered in two versions: one designed to use the module's integrated antenna and one designed to connect to an external antenna using an onboard antenna connector. The kits provide access to all 25 IO pins and interfaces available on the ANNA-B112 modules through various connectors and interfaces. These interfaces include Arduino Uno R3 and Raspberry Pi header connectors.
