The STM32F3DISCOVERY allows users to easily develop applications with the STM32F3 Series based on ARM® Cortex®-M4mixed-signal MCU. It includes everything required for beginners and experienced users to get started quickly.

Based on the STM32F303VCT6, it includes an ST-LINK/V2 or ST-LINK/V2-B embedded debug tool, accelerometer, gyroscope and e-compass ST MEMS, USB connection, LEDs and push-buttons.
The STM32F3DISCOVERY discovery board does not support the STM32F313xx MCUs (1.65 V to 1.95 V power supply).
