Papilio DUO-512KB

PRODUCT DETAILS

We live in exciting times where we can create masterpieces with the Arduino and marvels with the Raspberry Pi. Where we can use technology as a canvas to create things that amaze and amuse our friends and family. Wouldn't it be great if we could take the same technology that has been the staple of rocket scientists and put it in our creative arsenal?

Why can't we just draw up the circuits that we want to use? With the right software and circuit libraries we can! Let's put a full circuit lab on a chip, pair it with an easy to use Arduino-Compatible chip, and sprinkle in a generous helping of debugging tools. 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!

Hardware

The Papilio DUO is a third generation Papilio board.

Extensible - The first thing that people always ask for is the ability to use their Arduino shields. Seeed Studio 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. Seeed Studio 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.

Software and Features

The Papilio DUO is much more then just hardware. In fact, the software is the secret sauce that sets the DUO apart from other FPGA boards. It lets you draw up circuits without investing time and energy in learning VHDL/Verilog.

We start with the Arduino IDE (Integrated Development Environment) and supercharge it by adding circuits into the mix. We bring all of the pieces needed to draw and debug your very own circuits in one place. It's an easy and seamless user experience that we call Papilio DesignLab for use with both Windows and Linux.

Papilio DesignLab

We start with the Arduino IDE but every sketch now has a circuit associated with it - editing and debugging circuits is just a click away!

Simply draw and debug your circuits!

Click on the "Edit Circuit" button and simply draw your circuits using the Xilinx ISE schematic editor and our Papilio Circuit Library.
