SKU CH-GDN6-EY1KJ

In-circuit debugger and programmer for STM8 and STM32 microcontrollers via USB

  • Product typeSingle Board Computers
  • In-circuit debug and program STM8 and STM32 MCUs
  • SWIM and JTAG/SWD interfaces connect to target boards
  • USB full-speed link works with STVD and STVP tools
  • Compatible with Atollic, IAR, Keil and TASKING IDEs
  • Powered directly from the USB 5 V supply

ST-Link/V2 Debugger for STM8 STM32

The ST-Link/V2 is an in-circuit debugger and programmer built for STM8 and STM32 microcontrollers. It connects to a host computer through a USB full-speed interface. The device draws 5 V power directly from the USB connector. Developers use it to load firmware and debug code on target boards.

Suits engineers working with STM8 or STM32 chips

This tool suits engineers who need SWIM, JTAG or SWD access to STM8 or STM32 devices. It works with ST Visual Develop, ST Visual Program, Atollic, IAR, Keil and TASKING environments. Buyers who need support for other microcontroller families should look at a different debugger.

USB full-speed interface decides compatibility

The single specification that decides fit is the USB full-speed link to the host PC. Your development machine must provide a standard USB port that can supply 5 V power. If your workflow relies on a different host connection, this programmer will not integrate.

Questions about this item

What USB connector does the ST-Link/V2 use for power and data?

The debugger draws 5 V from a standard USB full-speed connector, which also carries the SWIM and SWD/JTAG signals to the host PC.

Which wiring step is most often missed when connecting the debugger to a target board?

Forgetting to link the SWDIO/SWCLK pins (or the single SWIM line for STM8) and a common ground between the ST-Link/V2 and the application board prevents communication.

When should the 20-pin JTAG/SWD cable supplied with the unit be replaced?

Replace the ribbon cable if the insulation cracks, pins bend, or intermittent connection errors appear during debugging sessions.
