The STLINK-V3MINIE is a stand-alone debugging and programming tiny probe for STM32 microcontrollers, portable and easy-to-use. Onboard JTAG/SWD interfaces for communicating with STM32 microcontroller, also provides a virtual COM port for the host PC to communicate with the target microcontroller through one UART.

Features:

Tiny 15 mm × 42 mm stand-alone debugging and programming probe for STM32 microcontrollers
Self-powered through a USB Type-C connector
USB 2.0 high-speed interface
Probe firmware is updatable through USB
Support drag-and-drop Flash programming of binary files
Two color LEDs: communication, power
JTAG communication support up to 21 MHz
SWD (Serial Wire Debug) and SWV (Serial Wire Viewer) communication support up to 24 MHz
Virtual COM port (VCP) up to 15 Mbps
1.65 to 3.60 V application voltage support

Two colors LED indicates both power and communication.

1. USB Type-C connector
2. Power LED indicator pad (LED is not soldered here)
3. STM32F723 MCU
4. BTB (board-to-board) card edge connector pads
5. STDC14 debug connector
6. COM LED Indicator

The LED is blinking red: the first USB enumeration with the PC is taking place.
The LED is red: the communication between the PC and STLINK-V3MINIE is established.(end of enumeration).
The LED is blinking green/red: data are being exchanged between the target and the PC.
