Overview

STLINK-V3MINIE is a stand-alone debugging and programming tiny probe for STM32 microcontrollers.
The JTAG/SWD interfaces are used to communicate with any STM32 microcontroller located on an application board.
STLINK-V3MINIE also provides a Virtual COM port interface for the host PC to communicate with the target microcontroller through one UART.
STLINK-V3MINIE is a portable version easy‑to‑use debugger and programmer including STDC14 interface with its flat cable and onboard pads for board‑to‑board (BTB) card edge connector.
Supports all STM32 series microcontrollers with JTAG/SWD interface.

Firmware Selection

STLINK-V3MINIE Types: "STM32 Debug +VCP" and "STM32 Debug + Mass storage + VCP".

STLINK-V3MINIE uses a USB interface to connect to a PC, and the driver is automatically installed by a toolset that supports ST-LINK. After connecting to the computer, the following driver will appear in the device manager, and a mass storage disk will appear when the computer is turned on.

There may be some computer drivers that are not successfully installed, as shown in the figure below, you need to install the drivers by yourself. Click here to install.
Right-click ST-Link Debug, ST-Link VCP Ctrl to update the driver.

The STLINK-V3MINIE downloader is connected to the STM32 target board using the JTAG/SWD interface through the adapter board.

STLINK-V3MINIE does not provide any power supply to the target application.

Connect the downloader to STM32 target board, power on the board, and you can read the information of the target board after connecting.

Open STM32CubeProgrammer, and you can use ST-LINK or UART to program.
How to program: Choose Erasing & Programming->Choose "hex" in "File programming"->Click to Connect the board->Press "Start Programming" to program the "hex" file.
