ST-LINK V2 Debugger/Programmer
For STM8 and STM32 Microcontrollers
The ST-LINK V2 is a development tool designed by STMicroelectronics for programming and debugging STM8 and STM32 series microcontrollers. It connects to a computer via USB and to the target microcontroller via a dedicated interface, facilitating firmware development and testing.
Pinout Configuration
The ST-LINK V2 features a 10-pin connector with the following pin assignments, often referred to as the "10P" connector:
| Pin Number | Label | Function |
|---|---|---|
| 1 | RST | Reset signal for the target microcontroller |
| 2 | SWDIO | Serial Wire Debug Data Input/Output |
| 3 | GND | Ground connection |
| 4 | GND | Ground connection |
| 5 | SWIM | Single Wire Interface Module (for STM8) |
| 6 | SWCLK | Serial Wire Debug Clock |
| 7 | 3.3V | 3.3 Volt power output for the target |
| 8 | 3.3V | 3.3 Volt power output for the target |
| 9 | 5.0V | 5.0 Volt power output for the target |
| 10 | 5.0V | 5.0 Volt power output for the target |
This device is compatible with both STM8 and STM32 microcontroller families, offering versatile debugging capabilities.
Physical Dimensions
