STLINK-V3SET debugger/programmer for STM8 and STM32
Introduction
The STLINK-V3SET is a stand-alone modular debugging and programming probe for the
STM8 and STM32 microcontrollers. This product is composed of the main module and the
complementary adapter board. It supports the SWIM and JTAG/SWD interfaces for the
communication with any STM8 or STM32 microcontroller located on an application board.
The STLINK-V3SET provides a Virtual COM port interface allowing the host PC to
communicate with the target microcontroller through one UART. It also provides bridge
interfaces to several communication protocols allowing, for instance, the programming of
the target through the bootloader.
The STLINK-V3SET can provide a second Virtual COM port interface allowing the host PC
to communicate with the target microcontroller through another UART (called bridge UART).
Bridge UART signals, including optional RTS and CTS, are available on the adapter board
only (MB1440). The second Virtual COM port activation is done through a reversible
firmware update, which also disables the mass storage interface (used for drag-and-drop
Flash programming).
The modular architecture of STLINK-V3SET enables to extend its main features through
additional modules such as the adapter board and B-STLINK-VOLT for voltage adaptation.

6 Quick start
This section describes how to start development quickly using the STLINK-V3SET.
Before installing and using the product, accept the Evaluation Product License Agreement
from the www.st.com/epla web page.
The STLINK-V3SET is a stand-alone modular debugging and programming probe for STM8
and STM32 microcontrollers.
•It support protocols SWIM, JTAG and SWD to communicate with any STM8 or STM32
microcontroller.
•It provides a Virtual COM port interface allowing the host PC to communicate with the
target microcontroller through one UART
•It provides bridge interfaces to several communication protocols allowing, for instance,
the programming of the target through the bootloader.
To start using this board, follow the steps below:
1. Check that all items are available inside the box
(V3S + 3 flat cables + adapter board and its guide).
2. Install/update the IDE/STM32CubeProgrammer to support the STLINK-V3SET
(drivers).
3. Choose a flat cable and connect it between the STLINK-V3SETand the application.
4. Connect a USB Type-A to Micro-B cable between the STLINK-V3SETand the PC.
5. Check that the PWR LED is green and the COM LED is red.
6. Open the development toolchain or STM32CubeProgrammer (STM32CubeProg)
software utility.
