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) .

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.
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.

Cortex ST-14 to 10 Pin Plug-of-Nails™ - No Legs
PCB End: 10 Pin Plug-of-Nails™ No Legs
Debug End: 14 Pin IDC 0.05" Female (Mates with FTSH)
10-Pin "No Legs" TC2050 Plug-of-Nails™ programming cable terminated with a 14-pin 0.05" pitch ribbon connector that mates with the STDC14 (FTSH-107) style micro-header found on the STLINK-V3 and STLINK-V3MINI.
Pins 3-12 of the STDC14 connector map to TC2050 footprint pins 1-10. STDC14 pins 1,2,13&14 are not connected. TC2050 Pin n connects to STDC14 Pin n+2
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.
Debug End: 14 Pin IDC 0.05" Female (Mates with FTSH)
10-Pin Legged TC2050 Plug-of-Nails™ programming cable terminated with a 14-pin 0.05" pitch ribbon connector that mates with the STDC14 (FTSH-107) style micro-header found on the STLINK-V3 and STLINK-V3MINI.
Pins 3-12 of the STDC14 connector map to TC2050 footprint pins 1-10. STDC14 pins 1,2,13&14 are not connected. TC2050 Pin n connects to STDC14 Pin n+2
2. SWD using the Cortex STDC14 connector with 6 Pin connector on target board
This cable provides signals for SWD protocol.
Connect the cable to the STDC14 connector.

Cortex ST-14 to 6 Pin Plug-of-Nails™ - No Legs
PCB End: 6 Pin Plug-of-Nails™ No Legs
Debug End: 14 Pin IDC 0.05" Female (Mates with FTSH)
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.
This product is intended to temporarily hold a TC2030 -NL ("No Legs") cable in place on a PCB. This solution will help when board space is at a premium and you need a hands free solution for debugging. Supplied as pack of 3.
We recommend keeping a few spare of these since the tiny boards are easy to misplace when working on the bench.
For a more robust solution consider a TC2030 legged cable.
Debug End: 14 Pin IDC 0.05" Female (Mates with FTSH)
6-Pin Legged TC2030 Plug-of-Nails™ programming cable for use with STM32 processors with STLINK-V3 and STLINK-V3MINI.
Note: This STDC14 cable was previously known as TC2030-CTX-ST14.

See also the TC2030-CTX-NL-STDC14 "No Legs" version of the cable with footprint that saves over 66% of the board space needed by typical FTSH-107 style micro headers!
If you need all 14-pins connected to your target board see instead the TC2070-IDC-050 cable.

Cortex ST-14 to 14 Pin Plug-of-Nails™ - No Legs
PCB End: 14 Pin Plug-of-Nails™ No Legs
Debug End: 14 Pin IDC 0.05" Female (Mates with FTSH)
14-pin Plug-of-Nails™ programming cable - No Legs Version

For TC2070 footprint specifications, please download the similar TC2070-IDC-NL Datasheet below (pdf)
See also TC2070-IDC-050 (legged) version.
Note that for many applications where 14-pin connectors are natively used by a debugger (such as MSP430, TI and ADI DSP's, Renesas MCU's etc) we offer some excellent alternative solutions that in many cases can reduce the footprint size on your PCB to 6 or 10-pins as well as reducing the price per cable.
GRIP-14 is used to hold a TC2070 -NL cable to the PCB.
The GRIP presses onto the three alignment pins from underneath the PCB and grips tightly. It is non-conductive.
This is one pack, three in a pack.
Note on GRIP-14 Usage
The GRIP-14 is intended for semi-permanent attachment of a 14-pin NL cable (such as the TC2070-IDC-NL) to a PCB for debugging or development. Due to the strong spring force of the 14-pin NL connector, the GRIP-14 often struggles to hold the cable securely and may not work well. While some customers have used it successfully for long-term attachment, results vary, and in many cases the cable will pop off from the force of the 14 spring pins.
Installing the GRIP-14 requires firm pressure to push the alignment pins into the GRIP under the board. The safest method is to position the GRIP on a flat surface and press the connector straight down. Pressing with fingers alone can slip and may cause injury. The GRIP-14 is not designed for frequent insertions or removals.
We continue to offer it due to customer demand, but please be aware it may not provide a reliable connection in all situations. Contact us if you’d like help exploring alternative solutions.
