It supports SWIM and JTAG/SWD interfaces, offers broad voltage compatibility (1.65 V to 5.5 V), and integrates seamlessly with popular development environments like STVD, Atollic, and IAR, making it an essential tool for professional embedded developers seeking efficient, reliable debugging and programming. ## Description 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 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.
