Does nRF54L15dk v1.0.0 P19 (debug out) work with long cables?

[Fridtjof]

Hello, Nordic Support!

I have some problems with programming my custom boards using my nRF54L15dk v0.9.1, when I use a setup with long cables (or several cables & adapters). According to Asbjørn 9 months ago, the circuitry was supposed to be changed for v1.0.0 of the dev kit. Before I buy one or more new nRF54L15dk, can you confirm that v1.0.0 of the dev kit can program external boards through longer cables?

10cm max will be what is guaranteed for the 1.0.0 still. Will work better with different operating voltages compared to the earlier versions.

Thanks for the quick answer! Which voltages have been improved? I'm working with a 3v3 board.

The improvement is if the OBD on the DK and the target have different voltages. On the version you have we state you should set the DK VDD to the same as the external voltage to program external targets, this should not be an issue with the 1.0.0 boards.

Alright, thank you again!
