u-blox ANNA-B412-00B Bluetooth 5.1 Bluetooth module - 802.15.1

Instructions:

The u-blox ANNA-B412 Bluetooth 5.1 Low Power Module (U-connect) combines Bluetooth 5.1, an embedded Arm® Cortex-M4 microcontroller with FPU, and an integrated antenna in a compact 6.5mm x 6.5mm system-level package (SiP). The ANNA-B412 module is based on the Nordic Semiconductor nRF52833 chip. The device is equipped with U-connectXpress software, which supports u-blox Bluetooth low-power serial port services, GATT clients and servers, beacons, Bluetooth Remote, NFC™, and sync peripherals and central devices. u-blox u-connectXpress software enables hosts to easily configure connections via commands with the UART interface.

The ANNA-B412 module provides excellent security through Secure Boot, which ensures that the module is only booted with certified U-connectXpress software and therefore has excellent security. Thanks to Bluetooth 5's long-range capabilities, the ANNA-B412 also has greater communication range and reliable connectivity.

The ANNA-B412 Bluetooth 5.1 module comes with an internal chip antenna (which can be easily integrated into the final product) and an antenna pin (which can use an external antenna of your choice). The ANNA-B412 is globally certified for use with internal or external antennas. To ensure its ability to work in harsh professional environments, the module is industrial-grade, ISO 16750 compliant and supports an extended temperature range from -40°C to +105°C.
