Howdy. I’ve completed my first custom PCB design using kicad. It’s a simple device based around the MB-N2 with a couple push-buttons. After reading the documentation I removed as much optional circuitry as possible. You can see my other post here.
After soldering everything and connecting SWDIO and SWDCLK to my DAPlink v1.0, unfortunately it fails to flash. I’ve confirmed that flashing the same program on the Nano 2 works fine. I also used a multimeter to double check all my soldering and PCB connections.
I have a feeling I might have missed something obvious that I’m just not seeing. I’ve included an image of my simple circuit. Any ideas what might be wrong?
