STLINK-V3PWR Connection to legacy targets

[Clyde_S]

How does one connect the STLink debug port to an older target with 0.025 square posts on 2.54 mm ptch for the debug connections?  As best I can tell, the supplied cables only support 1.27 mm pitch,

I finally got around to using my STLINK-V3PWR or trying. The issue is lack of thought on STM side, one simple adapter like all those ARM adapters but with a 10 pin 1.27mm pitch connector instead of the 2.0mm pitch they have. I purchased the V3PWR since it has a type C connector instead of the micro USB connector and all the power stuff my standalone power board does but with a case. I think I'll have to make a cable, after hunting for several hours I see no solutions. I had one of these https://bit.ly/4g6lPst laying around, with some soldering and crimping it's a start. A real solution would be a bundle like this https://bit.ly/3D9dA0l with a 1.27mm pitch 10 pin instead of the 2mm pitch 10 pin connector.

Thank you, Kevin.  I too purchased the device without paying close attention to the connecting cable.  Shame on me as I worked this same issue in another job with TI processors/debuggers.  It is sad that without the adapter I will make, the promise of good power profiling and correlation with the  running firmware is lost.

I will have to cobble up to solve it, or engineer my own board.
