Description
The STEVAL-BCNKT01V1 integrated
development and prototyping platform for
augmented acoustic and motion sensing for IoT
applications builds on the listening and balancing
capabilities of the human ear. With the expanded
capabilities of its starter kit, BlueCoin lets you
explore advanced sensor fusion and signal
processing functions for robotics and automation
applications with a 4 digital MEMS microphone
array, a high-performance 9-axis inertial and
environmental sensor unit and time-of-flight
ranging sensors. A high-performance
STM32F446 180 MHz MCU enables real-time
implementation of the very advanced sensor
fusion algorithms like adaptive beamforming and
sound source localization, with ready-to-use,
royalty-free building blocks. The BlueCoin can
connect via the on-board BLE link to any IoT and
smart industry wireless sensor network.

STEVAL-BCNCS01V1 - BlueCoin Core System board features
Very compact module for motion, audio and environmental sensing and Bluetooth low
energy connectivity with a complete set of firmware examples
Main components:
STM32F446 – 32-bit high-performance MCU (ARM® Cortex®-M4 with FPU)
4x MP34DT04-C1 – 64dB SNR Digital MEMS microphone
LSM6DSM – iNEMO inertial module: 3D accelerometer and 3D gyroscope
LSM303AGR – ultra-compact high-performance eCompass module: ultra-low
power 3D accelerometer and 3D magnetometer
LPS22HB – MEMS nano pressure sensor: 260-1260 hPa absolute digital output
barometer
BlueNRG-MS – Bluetooth low energy network processor
BALF-NRG-01D3 – 50 Ω balun with integrated harmonic filter
STBC03JR – linear battery charger with 150 mA LDO 3.0 V
External interfaces: UART, SPI, SAI (Serial Audio Interface), I²C, USB OTG, ADC,
GPIOs, SDIO, CAN, I2S
SWD interface for debugging and programming capability
The Bluetooth radio power output is set by default to 0 dBm; the FCC and IC
certifications refer to this operating value. The power output can be changed up to 8
dBm by reprogramming the device firmware, but this change will require an update of
the FCC and IC certifications, with additional radio emission tests to be performed.
