Rapid Prototyping with the Papilio
Overview
The Papilio has been designed with the intention of making it easy to add peripherals. The Papilio One provides six 8-bit Wing slots that allow hardware modules to be snapped in. We call these hardware modules "Wings". Wings are open source modules that can give you a jump start in prototyping your latest concept.
Wing Library
A growing library of Wings provides the basic hardware building blocks that can be used to quickly test out your ideas. There are a collection of basic modules available through the Gadget Factory store and a Wing Playground allows more exotic user designs.
Design your own Wing
EAGLE CAD templates make it a breeze to define your own custom Wings. Wings are easy to develop because there are no pin location requirements. Just add your desired component to the EAGLE schematic, connect it to the I/O pins that are most convenient, and let the autorouter take care of the routing. Wings take the worry out of making a new PCB, there are no placement mistakes to make, the FPGA can adapt to however you designed the Wing.
