ST-LINK/V2 and ST-LINK/V2.1 USB Debugger Programmer with Original STM Chip - 7Semi

The 7Semi ST-LINK/V2 and ST-LINK/V2.1 USB Debugger Programmer with Original STM Chip are reliable tools designed for STM32 microcontroller development. These USB-based programmers and in-circuit debuggers support both SWD (Serial Wire Debug) and JTAG interfaces, providing seamless connectivity for programming and real-time debugging.

They connect easily to STM32CubeIDE or third-party development environments like Keil, IAR, and Eclipse, offering extensive support for STM32 devices. The integrated ST-LINK server ensures firmware upgradability and simplifies switching between different target MCUs through adapter boards.

Designed for efficiency, they enable real-time debugging with features such as setting breakpoints, stepping through code, and monitoring variables directly. Full access to MCU memory and peripherals enhances system analysis and troubleshooting. Thanks to their compact size and robust performance, these tools are essential for both professional developers and hobbyists working on STM32-based projects.

Features:

  • USB Protection: 500mA self-recovering fuse safeguards USB ports.
  • Reliable Memory: Built with original STM32 128KB flash memory.
  • Dual Voltage Output: Supplies 5V and 3.3V for external devices.
  • Virtual COM Port: Enables easy serial debugging via VCP.
  • Firmware Updates: Supports Direct Firmware Update (DFU) mode.
  • High-Speed Debugging: Fast output via Single Wire Output (SWO).
  • USB 2.0 Compatible: Full-speed USB communication support.
  • Flexible Debugging: Supports JTAG, SWD, and SWV protocols.
  • Wide Voltage Range: Operates between 1.65V and 3.6V (5V tolerant).
  • Status Indicator: Communication activity shown via blinking LED.
  • Temperature Range: Works between 0°C and 50°C.
