Product details

Overview

B-F446E-96B01A from STMicroelectronics is a 96Boards Consumer Edition (CE) mezzanine development board built around the STM32F446RE MCU (ARM® Cortex®-M4, 180 MHz, LQFP100), integrated 9-axis IMU (accelerometer/gyroscope/magnetometer), pressure sensor, and digital microphone. It supports direct stacking onto 96Boards CE baseboards and enables rapid prototyping of environment-aware embedded systems with motion, acoustic, and atmospheric sensing.

For engineers reviewing the B-F446E-96B01A datasheet, B-F446E-96B01A pinout, B-F446E-96B01A application, or B-F446E-96B01A equivalent, this board delivers validated hardware integration for ARM® mbed™-enabled firmware development, USB-based virtual COM port/mass storage/debug interfaces, and dual expansion via Arduino™ Uno R3 and Grove™ connectors - critical for IoT edge node evaluation and sensor fusion validation.

Technical Context

The board implements the standardized 96Boards CE mechanical and electrical specification, enabling interoperability with compliant baseboards such as HiKey or DragonBoard 410c. Its STM32F446RE MCU provides deterministic real-time processing for sensor data acquisition, with dedicated hardware peripherals including I²C (for IMU and pressure sensor), SPI (for microphone), and USB 2.0 FS for composite device enumeration.

On-board ST-LINK/V2-1 provides full SWD debugging, drag-and-drop programming via mass storage, and simultaneous virtual COM port access - eliminating need for external debug probes. The integrated MEMS sensors are factory-calibrated and accessible through standardized drivers in STM32Cube and mbed OS.

FAQ

Does B-F446E-96B01A require an external debugger?

No. The board integrates ST-LINK/V2-1, providing full SWD debugging, drag-and-drop firmware programming via mass storage, and virtual COM port functionality using only the onboard micro-USB connection - no external probe is needed for development or field testing.

Which IDEs are officially supported for B-F446E-96B01A?

ST officially supports IAR Embedded Workbench, Keil MDK-ARM, GCC-based toolchains (including STM32CubeIDE), and ARM® mbed™ online compiler. All leverage pre-validated BSPs, HAL drivers, and sensor middleware from STM32CubeMX and X-CUBE-MEMS1 packages.

Can B-F446E-96B01A operate standalone without a 96Boards baseboard?

No. It is a mezzanine board requiring mechanical and electrical mating with a 96Boards CE-compliant baseboard (e.g., HiKey 960 or DragonBoard 410c) to provide power, host connectivity, and system-level interfaces - it lacks independent power regulation or host interface controllers.

Is the onboard microphone analog or digital?

The onboard microphone is a digital PDM (Pulse Density Modulation) type, directly interfaced to the STM32F446RE's DFSDM peripheral - enabling high-SNR audio capture with minimal external components and programmable decimation filtering.
