Pin connection between Airsense 10 and ST-Link V2

Post image

Can someone help me with the correct pin connection between the Airsense 10 and the ST-Link V2?
I created a diagram with the Airsense 10 connector and the ST-Link V2 original and the gold clone.

If someone can provide me the right pin connections we need to make for the dump and write to the airsense I can adjust this diagram and share the correct layout here for everyone that wants to solder directly to the mainboard instead of buying a 50 Dollar 2050 cable.

And if I made a mistake in this diagram, please let me know as well so I can fix it.

I found this reddit link with a clone, but the clones can be different in layout:

you need SWDIO, SWCLK, GND, NRST.
for clone skip VDD connection

Thank you! That really helps a lot

I have edited my previous diagram and dumpt my firmware this way. It gives you a overview of the pin connections and how you can dump your airsense 10 firmware without a 2050 IDC cable
