ST-Link V2 programmer for STM32 and STM8

This MCDODO ST-Link V2 unit is a single-board programmer and emulator for STM32F103C8T6 and STM8 microcontrollers. It targets hobbyists, students and embedded engineers who need a compact tool for firmware flashing and debugging via a 20 cm DuPont cable.

2.54 mm pitch header with DuPont cable

The board exposes a 2.54 mm pin header protected by 5 V output buffering that guards against accidental shorts during wiring. A supplied 20 cm DuPont lead allows flexible connection to target boards with varying pin sequences, and the interface legend is printed directly on the shell for quick reference.

Firmware V2.J17.S4 with automatic upgrade support

The programmer ships with firmware V2.J17.S4 and supports automatic firmware upgrades so the tool stays current without manual intervention. It relies on the ST-Link V2 protocol, so users needing higher-speed trace or newer core support beyond this standard should verify compatibility before purchase.

Questions about this item

Which SWD interface standard does the ST-Link V2 programmer use, and what firmware version does it ship with?

It uses the standard SWD interface and ships with firmware V2. J17. S4 already upgraded at the factory.

What pin pitch and cable length are needed to connect the programmer to a target board?

The header uses a 2.54 mm pitch and includes a 20 cm DuPont cable for flexible wiring.

How is the ST-Link V2 programmer installed, and which step do users often miss?

Connect the 20 cm cable to the 2.54 mm header matching the marked pinout, then install the ST-Link drivers and select the STM32F103C8T6 or STM8 target in your IDE; users often forget to align the cable to the silkscreen markings.
