Tiny DK Packs Sensor Fusion, Voice Capture, Bluetooth 5.0 Mesh Networking

STMicroelectronics’ STEVAL-BCN002V1B all-in-one IoT-node development kit (DK) features the company’s BlueNRG-Tile, a very small tile/coin built around STmicro’s BlueNRG-2 Bluetooth low energy 5.0 single-mode system-on-chip (SoC). The SoC provides control and processing power to a full complement of sensors, while also communicating via Bluetooth with a free iOS or Android demo app on a nearby smartphone. For multi-node applications, the BlueNRG-2 SoC, which is powered by an Arm Cortex-M0-core with up to 256KB of embedded flash memory, supports mesh networking up to 32k nodes, substantially extending the range of sensing and remote monitoring to any needs, from smart-home to large-scale industrial infrastructure.

 

Surrounding the BlueNRG-2 SoC, ST has packed a sensor portfolio that includes an accelerometer and gyroscope, a magnetometer, pressure, and humidity and temperature sensors, a microphone, and a FlightSense Time-of-Flight sensor. BlueNRG-2 SoC specs just 900 nA sleep current (with full data retention) and full-system stand-by power as low as 25 µA. More notably it also achieves ultra-fast wake-up capability, efficient execution of 9-axis inertial sensor fusion (running the ST MotionFX sensor-fusion code optimized for the Arm Cortex-M0) and streaming of real-time, low-latency data consuming just 1.4 mA at 25 Hz.

New VNA technologies enable mmWave broadband testing to 220 GHz, helping researchers and engineers to overcome test challenges and simplify mmWave testing.

Application development in the mmWave frequencies is growing. Broadband testing over hundreds of GHz of bandwidth is subject to repeatability/accuracy deficits, and engineers demand solutions to help overcome challenges and simplify mmWave testing.

 

Sampling now, the STEVAL-BCN002V1B Evaluation kit contains a BlueNRG-Tile (STEVAL-BCN002V1) and an STEVAL-BCN002V1D programming board to program and debug the BlueNRG-Tile. Checkout the datasheet.
