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) .

6-Pin Castellated Board-Edge connector programming cable for use with STM32 processors with STLINK-V3 and STLINK-V3MINI.
This special cable has a 6-pin ECV3-06 Edge-Connect™ connector and a 14-pin 0.05" pitch female IDC 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.
If you need all 14-pins connected to your target board see instead the cable.
For traditional ARM JTAG solutions using the 20-pin 0.1″ header as found on ST-LINK/V2 or the add-on Mezzanine board in STLINK-V3SET see here.
ECV3 is the third generation in the Edge-Connect™ family. ECV3 is NOT compatible with the previous Edge-Connect family and both will continue to be supported as current products into the future.
ECV3 makes some minor improvements adding greater robustness, improved convenience and is designed to be a mainstream product.
Edge-Connect™ is the patent-pending newest member in the family of Programming Connectors and Cables from Tag-Connect. ECV3-06 is the 6-pin connector.
By connecting to the literal edge of the PCB (not the surface near the edge like traditional edge-connectors) Edge-Connect™ is designed to essentially eliminate the wasted real-estate needed by JTAG programming and test connectors.
Edge-Connect™ is an Ideal solution for space-sensitive PCB’s and modules that don’t have room on the board for traditional connectors but which still need a means of programming firmware and testing.
We've designed Edge-Connect™so that we can offer low-cost, fast-turn, customized connector solutions to meet the unique requirements of your PCB - Contact Us if you have a custom requirement.

PCB snaps directly onto the Edge-Connect™
Zero Component Cost on the PCB
Maximizes available PCB real-estate
Eliminates the cost of a connector on every board
Requires just one tiny locating hole
Low profile edge access ideal for use with stacked PCB’s with no access headroom
Cant be connected backwards due to keyed feature

Alternative pitch? Three castellated edges? No problem!
No Header! - No Brainer!
Instead of using the usual space-costly Surface Mount or Plated Through-Hole connectors, Edge-Connect™ has springy gold-plated contacts that connect directly to the literal edge of the target PCB using edge castellation.
A Castellated PCB edge is a board edge that has plated through holes that are placed overhanging the edge of the board and typically made at little to no extra cost even from most cheap proto-board fab services (often a check box in the online quote is marked "Castellated Holes").
Castellated edges are commonly used on RF, WiFi, BLE and IoT sensor modules making them suitable for soldering as an SMT component onto host PCB’s using the castellated holes as pins. Edge-Connect™ allows test and programming and even debugging without first soldering the module to the host PCB. This makes it very useful for factory test and programming of the module.
ECV3-06-CTX has a castellation pitch of 1.27mm and requires a single tiny non-plated through hole to locate and hold the PCB in place.
New datasheet coming soon. Note that this product terminates in a 14-pin 0.05" IDC.
Note: ECV3-06-CTX-STDC14 with ribbon cable and IDC connector only supplied, Demo PCB not included.

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.
