Features: 1. Aluminum alloy USB drive case for secure and portable storage of the internal motherboard. 2. Interface labels are clearly marked on the shell for quick identification and ease of use. 3. Dual voltage output: 5V and 3.3V, supporting connection to both 5V and 3.3V target boards. 4. Laser-engraved markings on the shell—permanent and fade-resistant. 5. Internal motherboard includes a 500mA self-recovering fuse for enhanced protection of connected devices. 6. Dual-color (red and blue) LED indicators for real-time status monitoring. 7. Includes Dupont cables for flexible connectivity with various target boards. Compatibility & Functionality: 1. Supports full-series STM32 microcontrollers via SWD interface debugging; simple 4-wire connection (including power), high speed, and stable operation. Interface definitions are labeled directly on the shell. 2. Supports full-series STM8 microcontrollers via SWIM interface for programming and debugging. Compatible with common development environments including IAR Embedded Workbench (EWARM v6.20+, EWSTM8 v1.30+), STVD v4.2.1+, STVP v3.2.3+, and Keil MDK-ARM v4.21+. 3. Supports automatic firmware updates; pre-installed firmware version: V2.J17.S4. 4. Integrated 5V power output with protected I/O ports to prevent damage from accidental misconnections. Color: Random (no specific color selection available) Material: Aluminum alloy Note: This is the ST-LINK V2 debugger. It supports automatic firmware upgrades and is compatible with STM32 SWD and STM8 SWIM protocols for programming and debugging. Note: Appearance or labeling may vary slightly between production batches; this does not affect functionality or performance. Package Contents: 1 x ST-LINK V2 debugger
