# f407 大绿板: display and button pin mapping

> The f407 大绿板 investigation maps the pins connecting an ST7735S display module and five onboard buttons to an STM32F407VET6 development board. It provides display and GPIO probe programs, the author's reported pin assignments and a combined display-and-button demo.
