Hi Gmrck,
Thanks for contributing.
Yes you can take a look at the documentation: https://docs.nordicsemi.com/bundle/ug_nrf52840_dk/page/UG/dk/hw_debug_out.html

In regards to the original author: there's indeed an SWD interface on the XIAO board. The Groove Expansion board can be used with XIAO as well, to expose a dedicated conventional SWD port, as it is easier to connect this way.

My question to Nordic team though: do we have any tutorial in Academy or elsewhere on how to program all these 3rd party boards via the nrf52840 Dev Kit with the help of SWD connection?

Hi, is it a question ?
If you are asking if you can program XIAO nRF52840 Sense with the nRF5340 DK then the answer is not, without modification.
As far as I can see, the XIAO nRF52840 doesn't have SWD interface instead it allow you to program via USB port. Most likely it has a bootloader.

You may need to continue with Arduino or you need to find a way to connect SWD interface from the nRF5340 DK debug out port to the XIAO module.
