ST-Link-V3 Cable Selection

STLINK-V3 with 6-pin legged plug-of-nails connector

Back of ST-Link V3 showing ST-14 connector with programming cable attached

The STLINK-V3 (shown above) is ST’s latest debugger/programmer for their STM8 and STM32 microcontroller families.

STLINK-V3 is modular in that it has a “Main module” Hardware board (MB1441) which, ST documentation suggests, offers higher performance using a 14-pin 0.05″ connector, but also comes with an optional mezzanine board (MB1440) which offers more connections (presumably with potentially lower performance) including: Traditional 20-pin 0.1″ ARM connector (JTAG20), a 4-pin SWIM header, a 6-pin SWD header, and other pin headers offering access to VCP, SPI, UART, I2C, CAN and GPIO connections. With the mezzanine board fitted, this is known as the ST-Link V3 SET. This page covers cables solutions for the basic ST-Link V3 (without mezzanine board). Please see here for the ST-Link V3 SET cable solutions (with mezzanine board) .

Tag-Connect has a comprehensive set of solutions for use with ST-LINK V3 and we can also offer Custom Cables to suit your needs.

1. Full traditional JTAG, SWD using our TC2050-IDC-050-STDC14 or TC2050-IDC-NL-050-STDC14 10-pin Plug-of-Nails™ cables.

2. SWD using the TC2030-CTX-STDC14 or TC2030-CTX-NL-STDC14 cable providing a 14-pin 0.05″ Cable that plugs to the bottom of the STLINK-V3 and has a 6-pin TC2030 (-NL) connector on the other end. This cable provides signals for SWD protocol.

3. JTAG, SWD & UART using Cortex STDC14 to 14 Pin target board connector. TC2070-IDC-050 or TC2070-IDC-NL-050 14-pin cables providing a TC2070 14-pin connection to the PCB. The advantage to these cables is they provide all 14-pins including the UART.

1. Full Traditional JTAG, SWD using TC2050-IDC-050-STDC14

Compatible with all ARM processors.

Connect the TC2050-IDC(-NL)-050-STDC14 to the ST-LINK V3 via the STDC14 connector.

ST-Link V3 with TC2050-IDC-050-STDC14 programming cable

Both “legged” and “no-leg” cables come in the standard 6″ length. The TC2050-IDC-NL-050-STDC14 will require the TC2050-CLIP if you want a hands-free solution while debugging.

This product is intended to temporarily hold a TC2050-NL cable in place on a PCB. The solution will help when board space is premium and you need to perform a hands-free programming or debugging operation. For a more robust and convenient debugging connection consider using the TC2050 legged cable and footprint. Supplied as pack of 3. We recommend keeping a few spare of these since they are easily misplaced when working on the desktop. Over time they may lose some grip.

6-Pin "No legs" TC2030-NL Plug-of-Nails™ programming cable for use with STM32 processors with STLINK-V3 or STLINK-V3MINI that use the STDC14 connector. Note: This STDC14 cable was previously known as TC2030-CTX-NL-ST14. This special cable has a 6-pin TC2030 Tag-Connector and a 14-pin ribbon connector that mates with the STDC14 (FTSH-107) style micro-header found on the STLINK-V3 and STLINK-V3MINI providing the signals necessary for the SWD protocol on the STM32 MCU including SWO. See also the TC2030-CTX-STDC14 "Legged" version of the cable more suitable for development work. If you need all 14-pins connected to your target board see instead the TC2070-IDC-NL-050 cable. For traditional ARM JTAG solutions using the 20-pin 0.1" header as found on ST-LINK/V2 or the add-on Mezanine board in STLINK-V3SET see here.
