Color Option:Silver/Red/Black/Brown

The ST-LINK V2 is a versatile in-circuit debugger and programmer for STM8 and STM32 microcontrollers. It connects via USB and supports real-time debugging, flash programming, and various development tools. Compatible with STM32CubeIDE and ST-LINK Utility, it offers reliable programming and debugging through SWD for STM32 and SWIM for STM8 microcontrollers.

General Specifications:

• Supported Microcontrollers:

  • STM8 (via SWIM interface)
  • STM32 (via SWD interface)

• Programming Protocols:

  • SWD (Serial Wire Debug) for STM32 microcontrollers
  • SWIM (Single Wire Interface Module) for STM8 microcontrollers

• USB Interface:

  • Connects to the host PC through a USB 2.0 full-speed interface (backward compatible with USB 1.1)
  • Provides power to the device through the USB connection

• Supported Software:

  • STM32CubeIDE (IDE and development environment)
  • ST-LINK Utility (for flashing and memory access)
  • STM8 ST Visual Programmer (STVP) (for STM8 devices)
  • Keil MDK-ARM, IAR Embedded Workbench (third-party tools)
  • Atollic TrueSTUDIO (for STM32)

• Debugging Features:

  • Real-time debugging and single-step execution
  • Breakpoint and watchpoint support
  • Read/write access to memory and peripheral registers
  • Flash programming and verification
  • Low-power modes debugging support

Electrical Characteristics:

• Input Voltage (Target): 1.65V to 3.6V from target MCU
• Supply Voltage (USB): 5V via USB (for powering ST-LINK V2 itself)
