Extension connectors
Six extension connectors are implemented on the STM32U5 Nucleo-144 board:
•
CN7, CN8, CN9, and CN10 as Zio connectors supporting ARDUINO
®
Uno V3
•
CN11 and CN12 as ST morpho connectors

The CN7, CN8, CN9, and CN10 Zio connectors are female connectors supporting the ARDUINO

standard. Most shields designed for ARDUINO
®
can fit the Nucleo board.
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.
