# jtag-wire-adapter
[]()  [](https://aisler.net/p/new?url=https://raw.githubusercontent.com/islandcontroller/jtag-wire-adapter/master/pcb/jtag-wire-adapter.kicad_pcb&ref=github)
A compact adapter board for connecting SEGGER J-Link debug probes to generic JTAG/SWD targets using a set of flying wires.

### Key features
* Snug-fit debug probe connector
* .100" pin header for flying wire connection
* Signal assignment printed on silk screen

## Overview
This adapter can be used to interface a SEGGER J-Link debug probe to a generic JTAG or SWD target, using .1" *DuPont*-style jumper wires. This low cost solution can be especially useful for academic users of J-Link EDU probes, as it doesn't require special connector hardware to be fitted on target project boards.
## BOM
The parts are generic and can be found pretty much anywhere on the internet.
| Designator | Description |
|------------|---------------------------------------------------------|
| `J1` | Right-angle socket header, 2x10 contacts, .100" spacing
Suggested: `SFH11-PBPC-D10-RA` (Digikey [`S9205-ND`](https://www.digikey.de/de/products/detail/sullins-connector-solutions/SFH11-PBPC-D10-RA-BK/1990098)) |
| `J2` | Right-angle pin header, 1x7 contacts, .100" spacing |
## Design Review and Validation
Prototype PCBs were fabricated in the EU at [**AISLER B.V.**](https://aisler.net/) using their integrated KiCad plugin. See [photos](#photos) for further details.
* The selected stacked-row header seems to be *just* short enough to accidentally fit with a column offset. A wider connector should be selected to prevent wrong connection.
* The "original" connector as used on other adpters is a *Sullins Connector Solutions* `SFH11-PBPC-D10-RA` (available from Digikey as [`S9205-ND`](https://www.digikey.de/de/products/detail/sullins-connector-solutions/SFH11-PBPC-D10-RA-BK/1990098)).
A tool compatibility test was performed using a SEGGER J-LinkEDU emulator and a "blue pill"-type STM32 board.
