6-Pin Plug-of-Nails Cable with Legs and a 0.1″ IDC Connector
The Tag-Connect TC2030-IDC connects a debugger or programmer with a 6-pin 0.1″ IDC header to a 6-pad TC2030 footprint on your PCB, with no connector fitted to the board. Its legs clip into the footprint so the cable stays in place while you work. The NL (no-legs) variant needs a smaller footprint and is held by hand, with a clip or in a fixture.
Pin Assignment
The cable is wired straight through: TC2030 pad n goes to IDC pin n. The signal on each pin depends on the convention you use:
| Pad and IDC Pin | ARM SWD (Tag-Connect convention, as on the TC2030-CTX) | AVR ISP (standard 6-pin ISP header) |
|---|---|---|
| 1 | VTref | MISO |
| 2 | SWDIO | VCC |
| 3 | nRESET | SCK |
| 4 | SWCLK | MOSI |
| 5 | GND | RESET |
| 6 | SWO | GND |
PCB footprint: no solder paste on the contact pads. The legged footprint adds latch holes for the legs; see the drawings in our Tag-Connect cable guide.
Spring-Pin Contacts with Retention Legs
Each TC2030-IDC cable has six spring pins rated for over 100,000 insertion cycles. The plastic legs hold the plug on the board during programming or debugging, so no fixture or hand pressure is needed.
Debugger compatibility: plugs into tools with a 6-pin 0.1″ IDC header. For a SEGGER J-Link or ST-LINK/V2 with the 20-pin ARM header, add the ARM20-CTX adapter. For the Microchip Atmel-ICE AVR port, use the TC2030-ICESPI-LEMTA instead.
