2.1.2 ST-LINK probe
The ST-LINK is the JTAG/Serial Wire Debug (SWD) interface used to communicate with any
STM32 microcontroller located on an application board.
It is available as:
• Stand-alone in-circuit debugger
• Embedded in all STM32 hardware kits (Nucleo boards, Discovery kits, EVAL boards)
ST-LINK/V2 and ST-LINK-V3 are the main used versions.
Figure 8 shows ST-LINK/V2 and ST-LINK/V2- ISOL stand-alone probes on the right.
