7.3 Arduino Uno V3 connectors
CN4, CN5, CN6 and CN7 are female connectors compatible with Arduino standard. Most
shields designed for Arduino can fit to the STM32F746G-DISCO discovery board.
The Arduino connectors on STM32F746G-DISCO discovery board support the Arduino Uno
V3.
Caution: The IOs of STM32 microcontroller are 3.3 V compatible instead of 5 V for Arduino Uno.
