u-blox ANNA-B412 BLUETOOTH® 5.1 Module (u-connect)
u-blox ANNA-B412 BLUETOOTH® 5.1 Low Energy Module (u-connect) 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 ANNA-B412 Module provides top-grade security, thanks to Secure Boot, which ensures that the modules only boot up with authenticated u-connectXpress software. Leveraging Bluetooth 5 long-range features, ANNA-B412 also offers an extended communication range with reliable connections.
The u-blox ANNA-B412 Bluetooth 5.1 Module comes with an internal chip antenna for ease of integration in the end-product and an antenna pin for using an external antenna of choice. The ANNA-B412 is globally certified for use with the internal or external antenna. To ensure operation in harsh professional environments, the module is industrial grade and qualified according to ISO 16750, supporting an extended temperature range of -40°C to +105°C.
