A little while back I made vector representations for the EZ-Bv4 and IoTiny in an attempt to make it easier to create tutorials and wiring diagrams for these pieces of hardware. I apologize that I forgot to share them with you all until now. My plan was to add them to Fritzing but I haven't had time to learn how to build a complete model for each of them.
I created the vector files (.svg) in the open source software called Inkscape. If anyone would like to use, add to or scale them by all means help yourself!
