The ST-LINK is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families. The SWIM and JTAG/SWD interface is used to communicate with the STM8 or STM32 microcontroller located on your own application board.

STM8 applications use the USB full speed interface to communicate with STMicroelectronics’ 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.
