The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller familiesThe single wire interface module (SWIM) and JTAG/serial wire debugging (SWD) interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application boardSTM8 applications use the USB full-speed interface to communicate with the ST Visual Develop (STVD) or ST Visual Program (STVP) software. STM32 applications use the USB full-speed interface to communicate with Atollic IAR Keilor TASKING integrated development environments. 5 V power supplied by a USB connector
