OpenBench Logic Sniffer

An open source logic analyzer hardware design that provides a hardware platform for the SUMP logic analyzer at the lowest possible cost.

The Butterfly Platform is a modular FGPA and Microcontroller development system that puts you in control of your hardware choices. Add the power of an FPGA to the microcontrollers you are already familiar with, or jump straight into FPGA development. Either way you will benefit from standardized hardware peripherals that require no breadboarding, easy to use debugging tools such as a 100Mhz Logic Analyzer, and cost savings from a USB core that can be re-used with all microcontrollers and FPGAs. 

At the center of the Butterfly Platform is a FPGA core that creates connections between microcontrollers and peripherals without the need for any physical wiring, simply define connections in software. The FPGA core also provides advanced tools such as a 32 Channel 100Mhz Logic Analyzer without the need to connect any flying leads. Spend your time writing and debugging your application instead of cobbling together breadboards.

• Butterflies - A combination of Cocoons and Wings that create a product.
• Cocoons - Provide core functionality such as USB, power, and FPGA.

Butterfly One

The Butterfly One is a Gadget development board based on the Xilinx Spartan 3E FPGA (datasheet). It has 48 I/O lines, dual channel USB, integrated JTAG programmer, 4 power supplies, and a power connector. It provides everything needed to make Gadgets using Arduino compatible sketches or standard VHDL/Verilog. Hardware can be added without any soldering or bread boarding using the provided "Wing" slots. The Butterfly One places the focus on bringing Gadgets to life rather than reading through datasheets.

Butterfly Uno

Butterfly Uno is an FPGA development board that is 5V tolerant and has an Arduino footprint. The board can act as a shield and can use shields.
