The 32L476GDISCOVERY helps users to develop and share applications with the STM32L4 ultra-low-power microcontrollers.The Discovery kit combines STM32L476 features with LCD, LEDs, audio DAC, sensors (microphone, 3 axis gyroscope, 6 axis compass), joystick, USB OTG, Quad-SPI Flash memory, expansion and probing connectivity. It includes an embedded Ammeter which measures the MCU consumption in low power modes. An external board can be connected thanks to extension and probing connectors.

Virtual Com Port configuration
By default the Virtual Com Port is not enabled. To enable it, you need to close SB13 and SB16 solder bridge and ensure that SB15 and SB17 are open.
For more information, please refer to:
The following section describes known limitations of the platform. Note that general issues are tracked into the mbed repository available on GitHub.
This platform does not present any limitation.
