Embedded ST-LINK/V2-1

The ST-LINK/V2-1 programming and debugging tool is integrated in the STM32 Nucleo
boards.
The ST-LINK/V2-1 makes the STM32 Nucleo boards mbed enabled.
The embedded ST-LINK/V2-1 supports only SWD for STM32 devices. For information about
debugging and programming features refer to
debugger/programmer for STM8 and STM32, User
