Overview

The STLINK-V3MINIE is a portable, ultra-compact in-circuit debugger and programmer for STM32 microcontrollers. It features a high-speed USB 2.0 interface and supports JTAG, SWD, and Virtual COM port (VCP) protocols. This mini probe includes a voltage level shifter, allowing it to interface directly with target applications operating from 1.65V to 3.6V.

Why Choose This Part

Its primary advantage is the integrated level shifter which enables debugging low-voltage STM32 devices without external translation hardware. The probe supports high-speed communication and comes in a tiny form factor that fits easily in a laptop bag for mobile development.

Applications

Firmware Development
Providing real-time debugging and flash programming for STM32 targets via SWD or JTAG.
Field Updates
Using the compact form factor to perform on-site firmware updates or diagnostics on deployed hardware.
Hardware Validation
Utilizing the Virtual COM port to monitor UART telemetry from the target MCU during system testing.
Prototyping
Integrating with custom PCB designs via the 1.27mm pitch STDC14 connector for rapid code iteration.
