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.
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.
