B96B-F446VE

STM32F446 sensor board with 96Boards mezzanine support to use with 96Boards CE card

Overview

The STM32F446 sensor board enables users to prototype systems that are aware of their environment thanks to embedded sensors for movement, pressure and sound:

  • It can be plugged on a 96Boards CE card (such as the DragonBoard 410c) or simply be used in stand-alone mode.
  • Embedded sensors include a 9-axis accelerometer/gyroscope/magnetometer, pressure and microphone.
  • Capabilities may seamlessle be extender through its Arduino™ Uno and Grove™ connectors.
  • It does not require any separate probe as it integrates the ST-LINK/V2-1 debugger/programmer.

Getting started

Switch 96Boards mode to Stand-alone mode

  • To work in standalone mode
    • Add JP5 jumper
    • Add a 5V power supply on the Arduino +5V/GND pins of J4 connector
  • To work in 96Boards mode
    • Remove JP5 jumper

Nucleo ST-LINK/V2 driver installation and firmware upgrade

  • Install the ST-LINK/V2 driver before connecting the Nucleo board to your PC the first time. Follow this LINK for all details.
  • For optimum performances, ensure that the Nucleo ST-LINK/V2 firmware is upgraded to the latest version. Follow this LINK for all details.
