About this manual

The ST-LINK/V2 is an in-circuit debugger and programmer designed for STM8 and STM32 microcontroller families. It facilitates communication via SWIM and JTAG/SWD interfaces and supports direct firmware update (DFU). A specific variant, the ST-LINK/V2-ISOL, offers digital isolation between the PC and the target application board with a withstand voltage of up to 2500 VRMS.
