The ST Microelectronics STM32F3DISCOVERY is a Discovery board for the STM32F3 microcontrollers (MCUs). It includes everything required for beginners and experienced users to start developing applications quickly and easily.

The STM32F3DISCOVERY development board features a built-in ST-LINK debugger/programmer system.

What is the STM32 F3?
STM32 F3 series of microcontrollers are mixed-signal MCUs with both DSP and FPU instructions. It is based on ARM Cortex-M4 and offers up to 72MHz. The STM32F303VCT6 is the onboard chip which comes in a 100-pin LQFP package.

Who is it designed for?
Discovery STM32 F3 development board is suitable for both beginners and experienced designers. Whether you are looking to start your first MCU based project or a complex embedded device, this board will work for you.
