7 Expansion connectors
Six expansion connectors are implemented on the STM32H7Rx/7Sx Nucleo-144 board:
•
Zio connectors (CN7, CN8, CN9, and CN10) supporting ARDUINO
®
Uno V3
• ST morpho expansion connectors (CN11 and CN12).

standard. Most shields designed for ARDUINO

can fit the Nucleo board.
Caution: Most of the STM32 microcontroller I/Os are 5V‑tolerant, but a few of them are only 3V3‑compatible, while
ARDUINO
®
Uno is 5V‑compatible. Refer to the STM32H7Sx product datasheets for their I/O structure.
