Extension connectors

Six extension connectors are implemented on the STM32U5 Nucleo-144 board:
• Zio connectors (CN7, CN8, CN9, and CN10) supporting ARDUINO
• ST morpho connectors (CN11 and CN12)

Zio connectors supporting ARDUINO
The Zio connectors (CN7, CN8, CN9, and CN10) are female connectors supporting the ARDUINO
standard. Most shields designed for ARDUINO
Caution: Most of the STM32 microcontroller I/Os are 5 V‑tolerant, but few of them are only 3V3‑compatible, while
®
ARDUINO Uno V3 is 5 V‑compatible. Refer to the STM32U5 Series data brief and STM32U5xx product
datasheets for their I/O structure.
