IoT Expansion Card PCB CAD/brd files

Will be really glad if you guys can help me a Kicad / Altium / Eagle / anything CAD/schematic to design a new IOT card. Thanks

Hi folks, I also am looking for template PCB design files for IoT expansion card; something simple I can take and extend into something useful. The breadboard for example. Something I could then send off to PcbCart (or similar) for production. I currently use DesignSpark, but I’m sure we could find a way to process whatever format you’ve got.
