ST-Link V2 Programmer & Debugger

The ST-Link V2 Programmer and Debugger is a compact, low-cost in-circuit programming and debugging interface designed for STM8 and STM32 microcontroller families. An indispensable tool for embedded systems developers, electronics engineers, firmware programmers, and hobbyists working with ST Microelectronics microcontrollers and development boards.

Connecting directly to a host PC via USB, the ST-Link V2 enables full in-system programming, real-time debugging, and firmware flashing without removing the target microcontroller from the circuit. It supports both SWIM (for STM8) and SWD / JTAG (for STM32) communication protocols, providing broad compatibility across the ST microcontroller ecosystem.

Compatible with popular development environments including STM32CubeIDE, Keil MDK, IAR Embedded Workbench, and OpenOCD, the ST-Link V2 integrates seamlessly into professional and hobbyist workflows alike. The compact aluminium dongle form factor with a standard pin header interface makes it easy to connect to any target board, while the USB bus-powered design eliminates the need for an external power supply.
