NEW PRODUCT – Gameduino 3X Dazzler for Feather M4 by Excamera Labs


The Gameduino 3X Dazzler is an Adafruit Feather M4-compatible underwing that outputs HD picture and sound to any HDMI display or TV.

The Dazzler is ideal for game designers using CircuitPython, makers who want rich, responsive data and text visualizations, and anyone who wants superb visuals for their CircuitPython 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 Python-powered gaming system available today. There’s documentation and examples for using the ‘bteve` library, a C-accelerated SPI interface library for the graphics co-processor.

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.

Please note: This board is only for use with the Feather M4 Express, and you cannot solder stacking headers into the Feather – just use the regular headers that are included with the M4 Feather!

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
