7 Extension connectors
Six extension connectors are implemented on the STM32L5 Nucleo-144 board:
• CN7, CN8, CN9, and CN10 for Zio connector supporting ARDUINO
®
Uno V3
• CN11 and CN12 for ST morpho connector
The jumpers for voltage selection and IDD measurements are not described here.

Uno V3
The CN7, CN8, CN9 and CN10 Zio connectors are female connectors supporting ARDUINO
®
standard. Most
shields designed for ARDUINO
®
can fit the Nucleo board.
Caution:
The STM32 microcontroller I/Os are 3V3 compatible, while ARDUINO
®
Uno V3 is 5V compatible.
