Product details
Overview
STLINK-V3MINI from STMicroelectronics is a stand-alone USB-powered debug and programming probe for STM32 microcontrollers, supporting JTAG/SWD and Virtual COM Port (VCP) interfaces, 3–3.6 V target voltage, 5 V tolerant inputs, and drag-and-drop Flash programming on a 15 × 30 mm PCB.
For engineers reviewing the STLINK-V3MINI datasheet, STLINK-V3MINI pinout, STLINK-V3MINI application, or STLINK-V3MINI equivalent, key selection factors include SWV trace capability, STDC14 connector compatibility, DFU firmware update support, and cross-platform toolchain integration with Keil MDK-ARM, IAR EWARM, and GCC-based IDEs.
Technical Context
The STLINK-V3MINI embeds an STM32 Arm® Cortex®-M microcontroller to serve as a bridge between host PC and target STM32 devices, implementing protocol translation for JTAG, SWD, and UART over USB 2.0 high-speed interface. It delivers real-time SWV trace data and supports bidirectional VCP communication up to 15 MHz.
Its self-powered operation draws power exclusively from the USB Micro-B port, eliminating external power requirements, while integrated signal protection on all STDC14 lines ensures robustness against ESD and overvoltage during board-level debugging.

FAQ
Does STLINK-V3MINI support SWV trace streaming?
Yes. The STLINK-V3MINI supports Serial Wire Viewer (SWV) trace output over SWD, enabling real-time instruction and data trace capture from compatible STM32 targets when used with supported IDEs such as Keil MDK-ARM or STM32CubeIDE. Trace bandwidth depends on target clock speed and SWO pin configuration.
Can STLINK-V3MINI program non-STM32 devices?
No. STLINK-V3MINI is specifically designed and certified for STM32 microcontrollers only. It does not support programming or debugging of non-ST microcontrollers, including other ARM Cortex-M vendors or legacy 8-bit/16-bit devices, due to proprietary firmware and protocol stack limitations.
What operating systems are officially supported?
STMicroelectronics officially supports Windows 7/8/10, Linux 64-bit, and macOS. Driver installation is automatic on Windows and macOS; Linux users require udev rules for USB device access. ST-Link Utility and STM32CubeProgrammer are validated across all three platforms.
Is an external power supply required?
No. The STLINK-V3MINI is fully self-powered via its USB Micro-B interface and draws no auxiliary power from the target board. It provides regulated 3.3 V to the STDC14 connector's VAPP pin only for target voltage sensing-not for powering the target-ensuring safe, isolated debug operation.
