This page provides the complete Nucleo-H755ZI-Q Pinout diagrams for the STM32 Nucleo-H755ZI-Q development board. The Nucleo-H755ZI-Q is based on the STM32H755ZIT6 dual-core microcontroller running at up to 480 MHz (Cortex-M7) and 240 MHz (Cortex-M4) with 2MB flash and 1MB RAM. Diagrams include both Arduino / ZIO and Morpho header pin assignments with alternate function labels.
To view pin labels in detail, right-click any image and select Open image in new tab, then use Ctrl+Scroll to zoom.
