STM32L476VG MCU Discovery Kit

32L476GDISCOVERY

Overview

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.
