The Gameduino 3X Dazzler is an Arduino-compatible shield that outputs HD picture and sound to any HDMI
display or TV.
The Dazzler is ideal for game designers using Arduino or CircuitPython,
makers who want rich, responsive data and text visualizations,
and anyone who wants superb visuals for their Arduino project.
The graphics and sound are generated by a powerful BT815 EVE
embedded GPU.
The shield also has two Wii Classic ports for a plug-and-play game console.
With an easy-to-use graphics drawing API and dozens of samples and demos to use as starting points,
it’s by far the most powerful Arduino games system available today.
Every aspect of the design is open source and hackable:
the PCB design
the Verilog code for the HDMI, J1 CPU and system peripherals
the J1 CPU running on the FPGA
the J1's firmware that drives the Dazzler's extra features
The board itself has additional "hacking" interfaces: a JTAG port for FPGA reloading,
and a UART header for direct chat with the onboard FPGA.
Its unique combination of tightly-coupled GPU and FPGA opens up new creative possibilities.
As a truly open platform, the Dazzler can be anything you want it to be.
