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.

Search by pin name (e.g. PA9, PG14) or by function name (e.g. USART1_TX, QUADSPI_BK1), across all four header diagrams. Data is sourced from ST\’s official UM2408 Nucleo-144 User Manual and the STM32H755ZI pin database.
Note: the function list shown for each pin is that pin\’s full MCU-level alternate-function capability — not every function listed is necessarily wired or labeled on this specific connector; the diagram\’s own green/colored tags show only what ST has actually broken out at that position.
