LINK V2 JTAG / SWD Programmer & Debugger — STM8 to STM32 Microcontrollers

The LINK V2 is a USB JTAG/SWD in-circuit programmer and debugger compatible with the full range of STMicroelectronics STM8 and STM32 microcontrollers (M8 to M32 series). It provides a direct USB connection to the host PC and communicates with the target MCU via the standard SWIM (STM8) or SWD/JTAG (STM32) debug interface, enabling firmware flashing, real-time debugging, breakpoint setting, and register inspection without removing the MCU from the target board.

Typical Applications

Firmware Flashing: Program STM8 and STM32 microcontrollers in-circuit via SWIM or SWD without a bootloader — flash .hex or .bin files directly to internal flash memory
Real-Time Debugging: Set breakpoints, inspect registers, watch variables, and step through code in IAR EWARM, Keil MDK, or STM32CubeIDE during firmware development
Production Programming: Batch-program STM32 devices on a production line using STM32CubeProgrammer CLI with the LINK V2 as the programming interface
Bootloader Recovery: Recover STM32 devices with corrupted bootloaders or option bytes by direct SWD flash access, bypassing the UART/USB DFU bootloader
Embedded Systems Education: Learn STM32 development with a low-cost programmer compatible with all major STM32 development boards and Nucleo boards

FAQ

Q: Is this compatible with STM32 Blue Pill and Black Pill boards?
A: Yes. Connect the LINK V2 SWD pins (SWDIO, SWDCLK, GND, 3.3V) to the SWD header on the Blue Pill (STM32F103C8T6) or Black Pill (STM32F401/F411) board for programming and debugging.

Q: Does this work with STM32CubeIDE?
A: Yes. STM32CubeIDE detects the LINK V2 as an ST-LINK compatible programmer. Select ST-LINK as the debug probe in the Run/Debug configuration.
