STM32 development board designed for the ST official tool STM32F3DISCOVERY, and integrates various standard interfaces, pretty easy for peripheral expansions.


Open32F3-D is an STM32 development board designed for the ST official tool STM32F3DISCOVERY, which features the STM32F303VCT6microcontroller onboard.

The Open32F3-D supports further expansion with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with STM32F3 series microcontrollers.
