u-blox EVK-ANNA-B412 Evaluation Kit is a demonstration and development platform for the ANNA-B412 BLUETOOTH® 5.1 Low Energy Module (u-connect). The ANNA-B412 combines Bluetooth 5.1, an embedded Arm® Cortex®-M4 Microcontroller with FPU, and an integrated antenna into a compact 6.5mm x 6.5mm System in Package (SiP). The ANNA-B412 Module is based on the Nordic Semiconductor nRF52833 chip. This device is delivered with u-connectXpress software supporting u-blox Bluetooth Low Energy Serial Port Service, GATT client and server, beacons, Bluetooth Long Range, NFC™, and simultaneous peripheral and central roles. u-blox u-connectXpress software allows hosts to easily configure connectivity using AT commands over a UART interface.
The u-blox EVK-ANNA-B412 Evaluation Kit is offered in two variants. The EVK-ANNA-B412C includes the ANNA-B412 Module with an internal 2.4 GHz antenna (integrated into the SiP). The EVK-ANNA-B412U includes the ANNA-B412 Module and a U.FL antenna connector for external antennas.
The EVK-ANNA-B412 Evaluation Kit provides access to the 33 GPIO pins and interfaces supported on ANNA-B4 modules. The interfaces are available through various connectors, including Arduino Uno R3 and Raspberry Pi header connectors. The Evaluation Kit also supports simple USB drag-and-drop programming and a SEGGER J-Link debug interface.
