The NINA-B40 module of u-blox is built on Nordic nRF52833 chip, and as an open CPU, customer applications run on the built-in Arm Cortex-M4 and FPU. The NINA-B40 module integrates flash memory and RAM, and the application runs on the embedded Bluetooth low-power stack. Support Bluetooth low-power services, such as serial communication, GATT, beacon and mesh. For positioning applications, the NINA-B40 supports pointing functions, such as the arrival angle and departure angle of Bluetooth 5.1 specification. These methods determine the direction of signal transmission, which improves the positioning accuracy compared with the received signal strength (RSSI). The NINA-B40 can be used as both transmitter and receiver in DF applications.
The NINA-B40 provides a wider communication range or more reliable connection using Bluetooth 5 remote functions. In addition, the module supports NFC and ieee 802.15.4 with threads and Zigbee. A series of wired interfaces are available: UART, SPI, I (2) C, I (2) S, USB, QDEC, PDM, PWM and ADC. The key market segments are smart cities and buildings, industrial automation, healthcare and telematics. Specific applications include intelligent lighting, asset tracking, indoor positioning, low-power sensors, and wireless connectivity and configurable devices.
The NINA-B406 has an internal PCB antenna, while the NINA-B400 has a U FL connector can be used with external antenna. The internal PCB antenna provides a powerful low profile solution with high performance and wide range. The NINA-B40 series will be globally certified for use with internal antennas or a range of external antennas. This greatly reduces the time, cost and effort for customers to integrate Bluetooth with low power consumption in their design.
