1. OVERVIEW
Open429I-C is an STM32 development board designed for the STM32F429IGT6
microcontroller, consists of the mother board and the MCU core board Core429I.
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.
1.1. WHAT’S ON THE MOTHER BOARD
