The Papilio DUO has an FPGA on the top and the same chip that is used in the Arduino Leonardo（ATmega32U4）on the bottom. It's like having an Arduino with a full circuit laboratory connected to it！ For example、you can draw circuits to move pins、connect extra serial ports、or connect a bitcoin miner to the Arduino-Compatible chip. Just plug it into your computer using a USB cable、download our software and start drawing your own circuits.
FPGA Unleashed！
Our dream is to take the hardcore out of FPGA（Field Programmable Gate Array）and make it an amazing tool that anyone can use for creative technology projects.
Just like the Arduino team simplified C++ programming、we simplify FPGA design by providing easy to use drag and drop circuit libraries. We believe that drawing circuits will result in an amazing outpouring of creative FPGA projects！
Use the Papilio DUO to unleash your inner DaVinci. Draw and debug circuits on a chip without any soldering、breadboarding、or weird programming languages. Set your imagination free and put an FPGA in your creative arsenal！
