Introduction
The ST-LINK/V2 is an in-circuit debugger/programmer for the STM8 and STM32
microcontrollers. The single wire interface module (SWIM) and the JTAG/serial wire
debugging (SWD) interfaces facilitate communication with any STM8 or STM32
microcontroller operating on an application board.
In addition to providing the same functionalities of 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 1000 V
The USB full-speed interface enables communication with a PC and:
•
STM8 devices via ST Visual Develop (STVD) or ST Visual Program (STVP) software
(available from STMicroelectronics)
•
STM32 devices via IAR
STM32CubeMonitor integrated development environments.

ST-LINK/V2-ISOL In-circuit debugger/programmer with digital isolation a. The ST-LINK/V2 can communicate with targets operating below 3.3 V but generates output signals at this voltage level. STM32 targets are tolerant to this overvoltage. If some other components of the target board are sensible, use ST-LINK/V2-ISOL, STLINK-V3MINIE, or STLINK-V3SET with a B-STLINK-VOLT adapter to avoid the impact of overvoltage injection on the board. -
