ANNA-B112 - Stand-alone Bluetooth 5 low energy module

Compact stand-alone Bluetooth 5 Low Energy modules offering either open CPU architecture or pre-flashed u-blox connectivity software

The ANNA-B112 is an ultra-small, high-performing, standalone Bluetooth low energy module. The System in Package (SiP) module features Bluetooth 5, a powerful Arm® Cortex®-M4 microprocessor with FPU, and state-of-the-art power performance. The ANNA-B112 is delivered with u-blox connectivity software that provides support for u-blox Bluetooth low energy Serial Port Service, GATT client and server, beacons, NFC™, and simultaneous peripheral and central roles - all configurable from a host by using AT commands.

ANNA-B112 offers full flexibility for customers who prefer their application to run on the built-in Arm Cortex-M4 with FPU. With 512 kB flash and 64 kB RAM, it offers the best-in-class capacity for customer applications running on top of the Bluetooth low energy stack using SDK from Nordic Semiconductor or Arm Mbed. Additionally, interfaces such as SPI, I2C, and I2S are available, and features like NFC, Bluetooth mesh, AirFuel, and Apple HomeKit are also supported. In combination with Wirepas Mesh stack, ANNA-B112 can form large-scale industrial mesh networks for several applications, such as lighting, asset tracking, and metering.

The ANNA-B112 module also includes an integrated antenna providing a range of 160 m, and an antenna pin for design-in of an external antenna.

ANNA-B112 has full modular FCC approval, ISED approval, and RED compliance for Europe. Approvals for other countries are possible upon inquiry.
