STMicro Launches $10 STLINK-V3mini Mini Probe for STM32 MCUs

Last year, we reported STMicroelectronics launched STLink-V3 debugger & programmer for STM8 & STM32 microcontrollers that added I2C, SPI, and CAN interfaces compared the previous STLink-V2 model.

It’s not particularly expensive either at $35, but if you ever wanted something more compact and cheaper, the company has now introduced STLink-V3mini debugger going for under $10.

STLINK-V3Mini key features and specifications:

  • JTAG / serial wire debugging (SWD) specific features:
    • 3 V to 3.6 V application voltage support and 5 V tolerant inputs
    • JTAG communication support
    • SWD and serial wire viewer (SWV) communication support
  • Virtual COM port (VCP) specific features:
    • 3 V to 3.6 V application voltage support on the UART interface and 5 V tolerant inputs
    • VCP frequency up to 15 MHz
  • USB – Micro USB 2.0 connector for power and connection to host computer
  • Misc – 2x color LEDs: communication, power; STDC14 signals protection
  • Dimensions – 30 x 15 mm PCB

The debugger & in-circuit programmer supports drag-and-drop Flash programming, and direct firmware update support (DFU). It is delivered with 1.27 mm pitch STDC14 debug connector and STDC14 to STDC14 flat cable.

The STLINK-V3MINI debugger works with the company’s STM32CubeProgrammer software, as well as third-parties IDE such as Keil MDK-ARM, IAR EWARM, and GCC-based IDEs, including STMicro’s own free STM32CubeIDE.

You’ll find documentation and purchase link ($9.75) on the product page.

    1. It does not supports SWIM (STM8). If you check the normal STLink V3 they included an addon board (MB1440 I think) for the SWIM support.

      However the SWIM uses the TDO/SWO pin for communication so you just could add the same level shifter circuit around the StlinkV3-Mod/mini or if you have low voltage STM8 target it might work without it.

      You can find the reverse engineered schematics of the level shifting circuit here:

        1. Yeah the STM32F7 where probably chosen because they are more expensive, are not available on the Chinese market for pennies on the dollar and Chinese companies will probably have a harder time and less of an incentive to clone them.

          I love the fact that they integrated a VCP port on there.
