Nucleo-H753ZI Pinout Arduino ZIO and Morpho Header Diagrams

This page provides the complete Nucleo-H753ZI Pinout diagrams for the STM32 Nucleo-H753ZI development board. The Nucleo-H753ZI is based on the STM32H753ZIT6 microcontroller running at up to 480 MHz with 2MB flash and 1MB RAM. The H753ZI adds a hardware cryptographic and hash accelerator over the H743ZI but shares identical pin assignments.

Note: This board uses the newer MB1364 PCB revision (check your board’s own silkscreen to confirm). The diagrams below have been corrected specifically for that revision. The original Nucleo-H743ZI Pinout page covers the older MB1137 revision, which differs from MB1364 in several ZIO and Morpho pin assignments — see that page if your board has the older revision.

Find a pin or function:

Search by pin name (e.g. PA9, PG14) or by function name (e.g. USART1_TX, QSPI1_NCS) across all four header diagrams. Data is sourced from ST’s official UM2407 STM32H7 Nucleo-144 (MB1364) User Manual and the STM32H753 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.
