Key Features
Overview
The Tag-Connect ARM20-CTX adapter allows a standard 20-pin 0.1″ ARM/JTAG header on a debugger to drive a 6-pin TC2030 footprint for Serial Wire Debug (SWD) on your target, reducing PCB area and eliminating a mating connector on the board. It is designed for use with Tag-Connect TC2030-IDC (legged) or TC2030-IDC-NL (no-legs) Plug-of-Nails™ cables.
The adapter follows the ARM20 pinout and maps SWDIO, SWCLK, nRESET and SWO to the 6-pin TC2030, enabling SWD access from tools that expose the 20-pin ARM connector (e.g., J-Link, ST-LINK). For full JTAG use or where a 10-pin Tag-Connect footprint is preferred, see the TC2050-ARM2010 adapter. If the debugger has a fixed 20-pin cable or requires a male header extension (e.g., Lauterbach), the ARM20-CTX-M variant is available. These options cover compact SWD and full JTAG use-cases while preserving a tiny target footprint.
Engineers choose this adapter to save BOM and board space while using robust spring-pin connections for repeated development or production flashing. Related products at The Debug Store: TC2030-IDC cable, TC2030-IDC-NL cable, and TC2050-ARM2010 adapter.

Space & BOM savings
Straightforward SWD from ARM20
Flexible ecosystem
La carte d'adaptation Tag-Connect ARM20-CTX permet d'utiliser les câbles Tag-Connect TC2030-IDC pour les applications ARM SWD (Single Wire Debug). Bien qu'il soit destiné à être utilisé avec nos câbles brevetés TC2030-IDC (et TC2030-IDC-NL) Plug-of-Nails™, l'adaptateur peut être utile si vous préférez utiliser des embases à ruban 6 broches 0,1" sur votre PCB au lieu de l'embase traditionnelle à 20 broches.
Remarque : seul l'adaptateur est fourni. Le câble TC2030-IDC ou TC2030-IDC-NL est acheté séparément ; les câbles et le Segger JLINK visibles sur la photo ne sont pas inclus !

Frequently Asked Questions
Have a Question?
-
Why choose SWD over JTAG here?
SWD offers a low-pin-count alternative to JTAG for Arm Cortex devices, minimising target I/O usage.
-
What cables should I pair with it?
Use TC2030-IDC (legged) for hands-free retention in the PCB footprint, or TC2030-IDC-NL with a clip board.
-
Any orientation or pin-1 caveats?
Observe pin-1/keying and follow the datasheet mapping; some debuggers mount headers reversed, so check orientation.
-
Is SWO supported?
Yes—the mapping includes SWO (trace) on the TC2030 side per the datasheet.
-
When would I use ARM20-CTX-M instead?
Choose ARM20-CTX-M when your debugger’s 20-pin female ribbon can’t be removed or you need a male extension (e.g., Lauterbach).
-
Does ARM20-CTX carry all JTAG signals?
No—it is intended for SWD. For full JTAG via Tag-Connect, use TC2050-ARM2010.
-
Does it work with ST-LINK V2/V3?
Yes—ST-LINK tools with the 20-pin ARM connector can use ARM20-CTX for SWD to TC2030. Guidance is provided in Tag-Connect’s ST-LINK pages.
-
Is it compatible with SEGGER J-Link?
Yes—J-Link exposes the 20-pin ARM connector; ARM20-CTX maps this to TC2030 for SWD.
-
What does the ARM20-CTX do?
It adapts a 20-pin ARM/JTAG debugger header to a 6-pin TC2030 SWD footprint on your target.
