• USB 2.0 full-speed connection to PC
• Debug support with breakpoints and single-stepping
• Flash programming and memory verification
• LED status indicators for power and communication
• Compact design with protective case
• Compatible with STM32CubeIDE, Keil, and IAR

Technical Specifications

Applications

• STM32 firmware development and debugging
• Flash programming of production boards
• Real-time debugging with breakpoints
• Memory inspection and variable monitoring
• Bootloader recovery of bricked devices
• Educational use in embedded systems courses

Important Notes

• Install ST-Link drivers from ST website
• Connect SWDIO, SWCLK, GND, and 3.3V to target board
• Some clones require driver workaround on Windows 10/11
• Do not connect while target is powered externally without care
• SWO pin optional for printf-style debugging
