Papilio DUO - 2MB SRAMGadget Factory
Introducing the Papilio DUO - FPGA and Arduino-Compatible Chip Together at Last
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.
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!
The Papilio DUO is a third generation Papilio board. As such, it benefits from all of the tricks we've learned along the way as well as extensive feedback from the community. This past experience and community feedback drove the development of this board and puts the users needs first.
Extensible - The first thing that people always ask for is the ability to use their Arduino shields. We listened and started with an Arduino-Compatible footprint, retained support for six Papilio Wings, and even squeezed in support for one PMOD connector! Adding new hardware to your FPGA has never been easier, there is a huge selection of hardware out there just waiting for you to discover.
SRAM - Easy to use SRAM is a must. We've used SDRAM in the past and it was a big mistake! The strict timing requirements and interfacing caused fits for everyone. SRAM is asynchronous and dead easy to use, you will greatly appreciate the simplicity of SRAM in your projects.
