  • Open407Z-C Package B (STM32F4 Development Board)

    Open407Z-C is an STM32 development board designed for the STM32F407ZxT6 microcontroller, consists of the mother board and the MCU core board Core407Z.

    The Open407Z-C 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 STM32F4 series microcontrollers.
