ST-LINK/V2-ISOL

Overview

The ST-LINK/V2-ISOL is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families featuring digital isolation between the PC and the target application board. It supports the SWIM interface for STM8 and JTAG/SWD interfaces for STM32, ensuring safe debugging in environments where high voltages or noise may be present.

Why Choose This Part

The primary advantage is its 2.5 kV RMS high-voltage digital isolation, which protects both the debugger and the host computer from electrical surges on the target board. It integrates seamlessly with ST's official toolchain and supports a wide range of STM8 and STM32 devices with both 1.65V and 5.0V logic compatibility.

Applications

Getting Started

To begin, install the ST-LINK USB drivers and the STM32CubeProgrammer software or a compatible IDE such as STM32CubeIDE, Keil MDK, or IAR EWARM. Connect the debugger to your PC via a standard USB A-to-Mini-B cable and use the provided ribbon cables to connect to the target's JTAG, SWD, or SWIM header.
