Mouser stocks STMicroelectronics BlueCoin hearing and motion sensing platform
BlueCoin provides voice over Bluetooth low energy (BLE) and sensor fusion in one module. The STMicroelectronics module is now available from distributor, Mouser.
The BlueCoin hearing and motion sensing platform from STMicroelectronics is an integrated Bluetooth development system that incorporates low-power, high-performance nine-axis inertial and environmental sensors and a cluster of four digital MEMS microphones that are coupled with STMicroelectronics’ STM32F4 microprocessor.
BlueCoin is an augmented hearing and motion-sensing reference platform compatible with STMicroelectronics’ STM32 open development environment (ODE) and ST’s Open Software Expansion Libraries. The ODE function pack for ST’s MEMS microphones features advanced audio processing and audio output. The STM32Cube expansion pack software allows voice transmission over a Bluetooth low energy connection, making it suitable for audio entertainment, voice-controlled TV remotes, and wearable applications. The board can act as server and client simultaneously and can connect to any Internet of Things (IoT) or wireless sensor network.
The ODE function pack uses sound source localissation, beamforming, and acoustic echo cancellation to improve sound quality. Additional applications include PC control software compatibility to configure optimisations, beam direction, and source localisation.
The BlueCoin board offers sensor fusion through integrated inertial modules, a nano pressure sensor, and an array of four MEMS microphones with a low-power ARM-based STM32 F4 series microcontroller. An ST BlueNRG-MS network processor provides the Bluetooth low energy connectivity, while an STBC03 Lithium-Ion battery charger IC provides power management on the board.
