The Butterfly Light is an open source, modular FPGA development board. It is comprised of the USB Cocoon and the Spartan 3E Cocoon which paired together create the Butterfly Light FPGA development board. The Butterfly Light is best suited for developers who prefer to create their own daughterboards instead of utilizing the Wing peripheral system. The Butterfly Light exposes the maximum amount of I/O of all available Butterflies. It is also well suited for use with the Logic Analyzer software which implements a 100Mhz, 32 channel Logic Analyzer.
