The STMicroelectronics ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 range of microcontrollers.
The ST-LINK/V2 comes with a USB A to mini B cable which plugs directly into your PC and provides power to the module. This device communicates with the STM8 and STM32 MCUs via an application board. This is done via the SWIM (single wire interface module) and JTAG/SWD (serial wire debugging) interfaces.
