CN5, CN6, CN8 and CN9 are female connectors compatible with Arduino standard. Most 
shields designed for Arduino can fit to the STM32 Nucleo boards.

The Arduino connectors on STM32 Nucleo board support the Arduino Uno Revision 3.

For compatibility with Arduino Uno Revision 1, apply the following modifications:
•

SB46 and SB52 should be ON, 

•

SB51 and SB56 should be OFF to connect I2C on A4 (pin 5) and A5 (pin 6 of CN8). 

The IOs of STM32 microcontroller are 3.3 V compatible instead of 5 V for Arduino Uno.
