STLINK-V3MINI, compact in-circuit debugger and programmer for STM32 microcontrollers


The STLINK-V3MINI is stand-alone debugging and programming mini probe for STM32 microcontrollers.

The JTAG/SWD interfaces are used to communicate with any STM32 microcontroller located on an application board.

The STLINK-V3MINI also provides a Virtual COM port interface allowing the host PC to communicate with the target microcontroller through one UART.

The STLINK-V3MINI is a portable version, easy-to-use debugger/programmer including STDC14 interface with its flat cable.

Key Features

  • Stand-alone probe
  • Approximately 15 x 30 mm high-density integration PCB, very small form factor
  • Self-powered through a Micro-B USB connector (does not provide power supply to the target application)
  • USB 2.0 high-speed compatible interface
  • Direct firmware update (DFU) support, to use with more future devices
  • JTAG / serial wire debugging (SWD) specific features:
    • 3 V to 3.6 V application voltage support and 5 V tolerant inputs
    • Delivered with 1.27 mm pitch STDC14 to STDC14 flat cable
    • Additional adapter board and 2.54 mm pitch 20-pin JTAG/SWD flat cable (extra accessories from Waveshare)
    • 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
  • Drag-and-drop Flash programming
  • Two color LEDs: communication, power
  • Includes STDC14 signals protection

Supported Software

  • STM32CubeProgrammer
  • Keil® MDK-ARM
  • SW4STM32
  • STVP
  • GCC-based IDEs

Supported Devices

  • All STM32 MCUs with JTAG / SWD interface

Specification Comparison among Different STLINK Versions

JTAG/SWD application voltage 3V - 3.6V 3V - 3.6V 1.65V - 3.6V 3V - 3.6V ST-LINK/V2 supports STM32 low-power devices
SWIM application voltage 1.65V - 5.5V N/A 1.65V - 5.5V 1.65V - 5.5V  STLINK-V3MINI doesn't support SWIM of STM8
SWV support YES YES YES NO only available for STM32 at present
Debug interface multi multi 2 1 STLINK-V3SET/MINI feature GPIO port besides the programming port
LED indicator two colors two colors two colors red color two colors LED indicates both power and communication, while red color LED indicates only communication



Note: the STM32 application board in the photo is NOT included.

Connect to PC

The STLINK-V3MINI should be connected to the PC via a USB Micro-B cable.

  • Before connecting, install/update the ST-LINK toolset to support the STLINK-V3MINI (drivers)
  • STLINK-V3MINI adopts an STM32 F7 microcontroller, supports USB2.0 high speed communication

Connect to STM32 applications

The STLINK-V3MINI can be connected to STM32 target applications on JTAG / SWD interfaces.

  • Connection Method A: connect to target application directly via the onboard STDC14 connector.
  • Connection Method B: connect to target application via the STLINK-V3MINI Adapter board.
STLINK-V3MINI connections


  • COM LED is blinking RED: the first USB enumeration with the PC is taking place.
  • COM LED is RED: communication between STLINK-V3MINI and the PC is established (end of enumeration).
  • COM LED is blinking GREEN/RED: data are being exchanged between the target and the PC.
