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. In addition to providing the same functionalities as the ST-LINK/V2, the ST-LINK/V2-ISOL features digital isolation between the PC and the target application board. It also withstands voltages of up to 2500 VRMS. 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. Comes with one USB stick and a couple pieces of female-female jumpers. You may want to peruse our jumper selection if you need more or different sizes. We wired it up to an ST32F205 and ran ST-Link, and worked great! You can even update the firmware on the dongle as necessary, it has a DFU bootloader (we unplugged/replugged it from USB to kick off the DFU process)
