8 Extension connectors
8.1 ST Zio connectors
For each STM32H7 Nucleo-144 board, the following figures show the signals connected by
default to the ST Zio connectors (CN7, CN8, CN9, CN10), including the support for Arduino
Uno V3.
Figure 18. NUCLEO-H743ZI2 and NUCLEO-H753ZI
CN7, CN8, CN9 and CN10 are female on top side and male on bottom side connectors.
They include support for Arduino Uno V3. Most shields designed for Arduino Uno V3 can fit
to the STM32H7 Nucleo-144 board.
To cope with Arduino Uno V3, apply the following modifications:
• SB55 and SB62 should be ON
• SB53/60/65 should be OFF to connect I
2
C on A4 (pin 9) and A5 (pin 11 of CN9).
