There is now a CAD model for the Moteino-TraceAnt here:
Thanks to the generous contribution of Donnie Plumly there are now Fritzing Parts available for Moteino. Check out this Github repository for the details. Here’s a video he put together that shows how he actually built the Moteino part in Fritzing:
Side note: although Fritzing is not the best PCB layout software, some folks find it visually appealing to start laying out a circuit in Fritzing and perhaps build a PCB from that if the schematic and routing requirements are pretty basic. It’s great for illustrations and getting started with basic schematic and circuit layout.
