Do you provide 3.3v power supply to the nRF52811?

When you open J-Link Commander, you should see the tool detects VTref=3.300V.

I'm using P20 pins, connecting VDD, SWDIO, SWDCLK, GND Detected and the RESET pins of the devkit to the corresponding ones in the nRF52811 but nRF connect (v3.6.1) programmer doesn't detect the nRF52811 only detects the nRF52840, is it suppose to or i'm missing something? :(

Thank you so much for your attention 🙂

Yes, that is correct. There is an on-board J-Link debugger on the nRF-DK, you don't need other j-link debuggers.

I notice that in page 32/32 of nRF52840 DK user guide says we can program/debug the target connecting it to P19 or P20, so I can connect the nRF52811 to the nRF52840 DK and program it, I don't need any J-Link probe, right? 🙂
