Key Features
Overview
SEGGER 8.06.16 – J-Link 6-Pin Needle Adapter connects a J-Link or SEGGER Flasher to a PCB that omits a mating connector or header. It adapts from the standard 20-pin 0.1″ J-Link/JTAG connector to a compact 6-pin spring-needle pattern intended for SWD-based bring-up and production programming. A tri-pin locating pattern ensures correct orientation, while high-reliability spring pins provide stable contact during test and programming.
This 6-pin variant targets SWD; if full JTAG or target-power pin support is required, consider the SEGGER 10-Pin Needle Adapter (8.06.04). For alternative compact connectors (e.g., Cortex-M 10-pin 0.05″), see the 50-Mil 10-Pin Patch Adapter, and for general J-Link probes visit J-Link BASE Compact.
Engineers choose the needle approach to save PCB area and remove BoM and assembly cost associated with fitted headers, particularly in space-constrained or high-volume designs. The footprint and pinout are widely documented, simplifying PCB library creation and production use.
What to know: Six pins support SWDIO, SWCLK, RESET, SWO (optional), VTref and GND; for JTAG (TMS/TCK/TDI/TDO) use the 10-pin needle adapter.

Questions and Answers
-
Will It Work with J-Link BASE/PLUS/PRO and SEGGER Flashers?
Yes, it is designed for the J-Link and Flasher families via the 20-pin 0.1″ connector. See also the J-Link BASE Compact.
-
What PCB Footprint Size Should I Plan For?
Use SEGGER’s published pad pattern from the datasheet. The footprint is very small (smaller than the 10-pin version's), which helps with dense layouts.
-
How Does This Compare to Bed-of-Nails Fixtures?
Versus custom bed-of-nails fixtures, a needle adapter needs no connector fitted to the PCB, only a small pad footprint, and its locating pins position it consistently for programming.
-
Any Workflow Tips for First Bring-Up?
Follow SEGGER SWD pin guidance (VTref, RESET handling, optional SWO). Verify pull-ups/downs per device vendor before first connection.
-
What If I Need a Different Connector Standard Later On?
SEGGER provides adapters such as the 50-Mil 10-Pin Patch Adapter and the Target Supply Adapter to cover other scenarios.
-
What Problem Does the 6-Pin Needle Adapter Solve?
It enables SWD debug/programming on boards without connectors, reducing BoM and PCB area while preserving J-Link workflows.
-
Which Signals Are Available on the 6-Pin Footprint?
VTref, SWDIO, SWCLK, RESET, GND and optional SWO for trace/printf. For JTAG signals, use the 10-pin version.
-
Does It Supply Power to the Target?
No, the 6-pin version is intended for SWD signalling. If you need JTAG and the 5 V target-power pin via needle connection, use the 10-pin needle adapter (8.06.04).
-
How Does It Ensure Correct Orientation?
A three-pin locating pattern keys the adapter so it only mates one way. This reduces operator error and rework.
-
Is This the Same as Tag-Connect?
The footprint is the Tag-Connect TC2030 pattern (SEGGER's footprint drawing carries Tag-Connect's part numbers); the signal assignment is SEGGER's. Check SEGGER's pinout drawing against your target before laying out the pads. The 10-pin variant includes a 5 V supply pin.
