Product Overview

The USB-based programmer and in-circuit debugger, ST-LINK/V2.1 and ST-LINK/V2, by 7SEMI, are specifically designed for STM32 microcontrollers. These tools facilitate the programming and debugging of STM32 microcontrollers using either the SWD (Serial Wire Debug) or JTAG (Joint Test Action Group) interfaces. Developers can interact with STM32 applications through the USB full-speed interface, connecting seamlessly with the STM32CubeIDE software tool or other third-party integrated development environments.

Featuring a robust embedded ST-LINK/V2 server, the ST-LINK/V2.1 and ST-LINK/V2 support firmware upgrades and offer user-friendly target MCU switching through corresponding adapter boards. They boast compatibility with a broad range of STM32 microcontrollers and seamlessly integrate with prominent third-party IDEs like Keil, IAR, and Eclipse.

These tools provide real-time debugging capabilities, allowing developers to set breakpoints, step through code, and monitor variables in real-time. Moreover, they grant access to the MCU's memory and peripherals, empowering users to analyze system behavior and identify potential issues.
