Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Description:

The u-blox ANNA-B402 Bluetooth ® 5.1 Low Power Module (developed CPU) integrates Bluetooth 5.1, embedded Arm® Cortex-M4 microcontroller with FPU, and integrated antenna in a compact 6.5mm x 6.5mm system-level package (SiP). The ANNA-B402 module is based on the Nordic Semiconductor nRF52833 chip. The device features 512kB of flash memory and 128kB of RAM, providing the necessary capacity for advanced applications developed with an open CPU architecture and the Nordic SDK. Wired interfaces such as UART, USB, SPI, I2C, I2S and GPIO can be used to connect peripherals.

The ANNA-B402 module supports Bluetooth direction finding, Angle of Arrival (AoA) and Angle of Departure (AoD) for location applications. These features provide a more precise position than using only the received signal strength. The ANNA-B402 offers extended communication range for more reliable connectivity over long distances via Bluetooth. Alternatively, the Wirepas mesh stack can be used to compose large industrial mesh networks.

In addition to Bluetooth low power consumption, it also supports ZigBee and Thread protocols and NFC technology.

The u-blox ANNA-B402 Bluetooth 5.1 module comes with an internal chip antenna (for easy integration into the final product) and an antenna pin (for use with the selected external antenna). The ANNA-B402 is globally certified for use with internal or external antennas. The module is industrial-grade, ISO 16750 compliant and supports an extended temperature range from -40°C to +105°C.
