Arduino Uno V3 compatible connectors

CN11, CN12, CN13 and CN15 are female connectors compatible with Arduino Uno V3 
standard. Most  shields designed for Arduino Uno V3 are also supported by the 
32F723EDISCOVERY board.

The Arduino connectors on 32F723EDISCOVERY board support the Arduino Uno V3.

Caution:

The I/Os of STM32 microcontroller are 3.3 V compatible instead of 5 V for Arduino Uno V3.
