ST-LINK/V2 STM8 and STM32 MCU USB JTAG in-circuit Debugger Programmer Emulator

ST-LINK/V2 STM8 and STM32 MCU USB JTAG in-circuit Debugger Programmer Emulator

The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families. The 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 board.

STM8 applications use the USB full speed interface to communicate with STMicroelectronic's ST Visual Develop (STVD) or ST Visual Program (STVP) software.

STM32 applications use the USB full speed interface to communicate with Atollic, IAR, Keil or TASKING integrated development environments.
