ST-LINK is a very low-cost, in-circuit debugger/programmer for the STM8L, STM8S and STM32. It connects to application or evaluation boards for programming and debugging via STMicroelectronics' SWIM single-wire connection for the STM8L and STM8S and via a JTAG standard connection for STM32 microcontrollers.
