Hello Kaja,

Thank you for the prompt reply (as well as for the valuable information)!

I am marking this question as "answered", but I may come back later with my schematic and layout (as you are proposing) if I feel the need.

Thanks again. Have a great day. A+ 🙂

Frank

Hi Frank,

the trace width on the DK is based on the substrate and distance to ground, and it's a 50 Ohm transmission line. The width of the track is 0.2 mm, but you have to choose your width of the track based on your pcb and design.

If you want me to do a review of your design as well, you can upload the schematic and layout.

Best regards,
Kaja
