Modular Debugger for STM32 and STM8

The STLINK-V3SET is a standalone in-circuit debugger and programmer designed for STM32 and STM8 microcontrollers. It targets engineers and developers who need a self-powered probe with modular extension support for embedded development and evaluation tasks.

USB High-Speed Probe with Multiple Adapters

Installation connects via a USB 2.0 high-speed Micro-B interface that also handles direct firmware updates. The kit includes flat cables for STDC14, MIPI10, and MIPI20 connectors at a 1.27 mm pitch, plus an adapter board for SWIM headers at a 2.54 mm pitch. Mismatched connector pitch or voltage selection outside the 1.65 V to 5.5 V range are the typical integration issues.

Voltage Coverage from 1.65 V to 5.5 V

The probe supports target application voltages from 3 V to 3.6 V for JTAG, SWD, and VCP interfaces, with 5 V tolerant inputs. The SWIM adapter extends the lower bound to 1.65 V and the upper bound to 5.5 V. Virtual COM port operation reaches 15 MHz on the STDC14 connector. Targets requiring voltages outside these windows or interfaces not listed are not supported.

Questions about this item

How do I verify the STLINK-V3SET is working after connecting it to my STM32 target?

The probe enumerates as a USB 2.0 high-speed device and exposes a Virtual COM port up to 15 MHz; successful JTAG or SWD connection and SWV trace confirm correct operation.

Which cables and adapters are included with the STLINK-V3SET and what must I source separately?

Flat cables for STDC14 to MIPI10, STDC14 and MIPI20 (1.27 mm pitch) are supplied; the MB1440 adapter board for SWIM (2.54 mm pitch) is not included.

Should I choose the STDC14 or MIPI10 debug connector for my STM32 board?

Use STDC14 when you need the Virtual COM port and SWV trace; MIPI10 (10-pin, 1.27 mm pitch) is smaller but lacks VCP.
