Product Description
The ST-LINK/V3SET is the flagship modular in-circuit debugger and programmer from STMicroelectronics. It represents a significant generational leap over the ST-LINK/V2, offering USB 2.0 High-Speed (480 Mbps) communication for drastically faster code flashing and real-time debugging.
Designed as a modular system, it consists of a main module and a complementary adapter board (MB1440). This architecture supports advanced multipath bridge functions, allowing users to communicate with target MCUs through SPI, I2C, CAN, and UART. Whether you are working in a professional lab or developing complex IoT systems, the ST-LINK/V3SET provides the most versatile and future-proof toolset for the entire STM8 and STM32 ecosystem.
Key Features
  • Next-Gen Speed: USB 2.0 High-Speed interface reduces programming time for large applications compared to older 12 Mbps tools.
  • Modular Connectivity: Includes the MB1440 adapter board for diverse connector types including STDC14, MIPI10, and MIPI20.
  • Multipath Bridge: Professional-grade USB-to-bridge interfaces for I2C, SPI, CAN, and GPIOs, enabling target programming via bootloaders.
  • Dual Virtual COM Port (VCP): Supports up to two VCPs for simultaneous debugging and communication with multiple target UARTs.
  • Direct Firmware Update (DFU): Native support for official 2026 firmware releases to ensure compatibility with newly released ST microcontrollers.
  • Drag-and-Drop Flash: Integrated mass storage interface allows for quick binary file programming by simply dragging files into the device’s folder.
Usage Guide
  1. Preparation: Install the latest STM32CubeProgrammer or ST-LINK USB Drivers (Version 2.0+).
  2. Modular Assembly: Use the main module for standard JTAG/SWD debugging. Attach the MB1440 adapter board if you require SWIM (for STM8) or bridge interfaces (SPI/I2C/CAN).
  3. Hardware Connection: Connect the Micro-B USB cable to your PC. The PWR LED should turn green, and the COM LED will initially be red.
  4. Firmware Sync: Upon first use, use the ST-LINK Upgrade Utility to ensure the device is running the latest 2026 firmware.
  5. Debugging: Select “STLINK-V3” in your IDE (Keil, IAR, or STM32CubeIDE). Ensure your target board is powered independently, as the ST-LINK/V3SET does not provide power to the target application.
Q: Does the ST-LINK/V3SET provide power to my target board?

No. The ST-LINK/V3SET is designed to monitor and match the target board’s voltage. You must provide an external power supply to your STM32/STM8 board during use.

Q: Can I use this for mass production programming?

Yes. Its high-speed interface and support for command-line programming via STM32CubeProgrammer make it ideal for business production environments.

Q: Is this version compatible with the STM8 series?

Yes, unlike the V3MINI versions, the ST-LINK/V3SET supports the SWIM interface for all STM8 microcontrollers through the included adapter board.

Q: How does this differ from the cheaper "Import Chip" V2 clones?

This is the official modular kit from STMicroelectronics. It offers significantly higher data speeds (480 Mbps vs 12 Mbps), bridge functions (I2C/SPI/CAN), and guaranteed compatibility with all official software updates in 2026.

Q: What operating systems are supported?

It is fully compatible with Windows (7, 8, 10, 11), Linux 64-bit, and macOS.
