Key Features
Overview
The Tag-Connect TC2030-SWIM links the SWIM connector of an ST-LINK/V2 to six pads on your STM8 board. Spring pins contact the pads, so the board carries no SWIM header.
Choose Legged or No Legs in the options above.
The Legged version clips into the footprint and stays in place without a fixture. The No Legs version (TC2030-SWIM-NL) needs a smaller footprint and is held by hand, with a TC2030-CLIP or in a fixture.
STM8 SWIM From an ST-LINK to Six Pads on Your PCB
The TC2030-SWIM is a TC2030-MCP cable modified with a 4-pin SWIM connector (the No Legs TC2030-SWIM-NL is built from the TC2030-MCP-NL). It plugs into the SWIM connector of an ST-LINK/V2, so you can program and debug STM8 microcontrollers through the 6-pin TC2030 footprint instead of a fitted header.
Options
| Option | Choice | Detail |
|---|---|---|
| Head | Legged | Legs clip into leg latch holes in the PCB, so the cable holds itself in place (TC2030-SWIM) |
| Head | No Legs | No leg holes, so a smaller footprint; hold by hand, with a TC2030-CLIP or mount it in a test fixture with a TC-MOUNT-6 bracket (TC2030-SWIM-NL) |
Pinout
| TC2030 Pin | SWIM Signal |
|---|---|
| 1 | VDD |
| 2 | DATA (SWIM) |
| 3 | RESET |
| 4 | Not connected |
| 5 | GND |
| 6 | Not connected |
Tag-Connect does not publish an overall length for the SWIM versions.
PCB footprint: the standard 6-pin TC2030 footprint. Legged and No Legs cables use the same contact pattern, so a board laid out for the legged footprint takes either cable. Leave the contact pads free of solder paste and keep tracks and vias out of the keep-out area. See our Tag-Connect cable guide for footprint drawings.
Spring-Pin Contacts
In Tag-Connect's cycle testing the spring pins last for well over 100,000 operations; Tag-Connect says the ribbon cable is usually the first part to fail.
Who It's For
Engineers who program or debug STM8 boards over SWIM and want six pads on the PCB instead of a fitted SWIM header.
| Device Family | Debugger or Programmer | Connection |
|---|---|---|
| ST STM8 MCUs, SWIM | ST-LINK/V2 | Plugs into the ST-LINK/V2's 4-pin SWIM connector |
| ST STM8 MCUs, SWIM | STLINK-V3SET | Plugs into the 4-pin SWIM header on the STLINK-V3SET's MB1440 adapter board (SWIM is only available through that board) |
When to Choose a Different Cable
This cable carries SWIM only. For STM32 over SWD with an ST-LINK/V2, Tag-Connect lists the ARM20-CTX adapter with a TC2030-IDC cable. With an STLINK-V3, it lists the TC2030-CTX-STDC14 (or the No Legs TC2030-CTX-NL-STDC14); for other Cortex debuggers, see the TC2030-CTX. For a Microchip ICD with an RJ12 socket, use the TC2030-MCP.
Compare the Versions
| Part Number | Head | Best For |
|---|---|---|
| TC2030-SWIM | Legged | Development and debugging: clips in and stays connected hands-free |
| TC2030-SWIM-NL | No Legs | Production programming, or debugging with a TC2030-CLIP; smaller footprint |
Both versions use the same six-pad contact pattern and pinout; only the head differs.

Questions and Answers
-
Does the TC2030-SWIM Work with the STLINK-V3SET?
Yes, with ST's MB1440 adapter board fitted. Tag-Connect lists both SWIM cables for the STLINK-V3SET, and ST provides SWIM only on the MB1440 board, on a 4-pin 2.54 mm header.
-
What Is the Difference Between the TC2030-SWIM and the TC2030-SWIM-NL?
Only the head. The TC2030-SWIM has legs that clip into leg latch holes and hold it on the board. The TC2030-SWIM-NL has no legs, so its footprint is smaller, and it is held by hand, with a TC2030-CLIP or in a fixture with a TC-MOUNT-6 bracket. The pinout is the same.
-
Can I Use the No Legs Cable on a Board Laid Out for the Legged Cable?
Yes. Tag-Connect says the No Legs connector can also be used with the legged footprint. It does not work the other way round: the Legged cable needs the leg latch holes, and the No Legs footprint does not have them.
-
Which TC2030 Pins Carry the SWIM Signals?
Pin 1 is VDD, pin 2 DATA (SWIM), pin 3 RESET and pin 5 GND. Pins 4 and 6 are not connected.
-
Is a Retaining Clip Included with the No Legs Cable?
No. The cable is supplied on its own. The TC2030-CLIP is sold separately, singly or as a pack of three.
