8 Connectors
Eight connectors are implemented on the Nucleo board:
• CN15: ST-LINK USB connector
• CN5, CN6, CN8 and CN9 for Arduino™ Uno V3 connector
• CN7 and CN10 for ST-Morpho connector
• CN1: USB User connector.
8.1 USB ST-LINK micro-B connector CN15
The USB connector CN15 is used to connect the embedded ST-LINK/V2-1 to the PC for
programming and debugging the Nucleo microcontroller.
