STM32 development board designed for the ST official tool STM32F429I-DISCO, and integrates various standard interfaces, pretty easy for peripheral expansions.


Open429I-C is an STM32 development board designed for the STM32F429IGT6 microcontroller, consists of the mother board and the MCU core boardCore429I.

The Open429I-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 STM32 series microcontrollers.
