Gameduino 3X adds a bright touchscreen to the Arduino. It features amazing graphics, audio and video from the FT815 GPU -- right in your hand. There are three models:

Gameduino is by far the most capable graphics shield for the Arduino, and many find it the easiest to use.

The Gameduino 3X Dazzler with HD HDMI out, dual Wii controllers, and many other features is now available from Crowd Supply, Amazon and the Excamera Store.

You can buy a Gameduino 3X for $39 from our online store. Same day shipping is free.

You can also buy from Amazon: Gameduino 3X 4.3" and Gameduino 3X 5".

The UK distributor Cool Components carries all models: Cool Components.



You can download the Gameduino library and tools on this page.

Example sketches

There are dozens of examples included with the Gameduino library, and many more in the Gameduino book. These samples here give an idea of what it can do.

About Gameduino 3X

The Gameduino 3X shield that adds a bright touchscreen, an embedded GPU, headphone jack, accelerometer and microSD slot to your Arduino - or anything else with an SPI interface. Everything you need to create compelling games -- right in your hand.

  • video output is in 24-bit color
    • Gameduino 3X 4.3" is 480x272
    • Gameduino 3X 7" is 800x480
    • Gameduino 3X Dazzler is 1280x720
  • OpenGL-style command set
  • Up to 2000 sprites, any size
  • 1 Mbyte of video RAM
  • smooth sprite rotate and zoom with bilinear filtering
  • smooth circle and line drawing in hardware - 16x antialiased
  • JPEG and PNG loading in hardware
  • built-in rendering of gradients, text, dials and buttons

Sound output is via an amplified headphone jack. The system supports a selection of built-in samples and instruments, and can also play samples from video memory, at up to 48KHz.

The BT815 can handle media in several formats directly. These save CPU memory, and mean simpler code on the CPU.

  • decodes JPEG and PNG images directly. No libraries required
  • for lossless image loading, decompresses (zlib INFLATE) directly
  • audio samples can be 8-bit linear, ulaw or ADPCM

Built into the GPU's ROM are:

  • high-quality fonts in 6 sizes
  • samples of 8 musical instruments, playable by MIDI note
  • samples of 10 percussion sounds

and of course you can load your own fonts and audio samples into the on-board 1 megabyte RAM.



Gameduino 3 is much like the first Gameduino, an SPI peripheral. The sdcard is also on SPI. Touch and audio functions are handled by the FT810, so take no extra pins. The full pinout (Arduino shield pin numbers) is

GND pwr Signal ground
5V pwr Main supply: 5-7V
11 in SPI MOSI
12 out SPI MISO
13 in SPI SCK
8 in GPU SEL
9 in SD SEL

For power, the shield needs 5-7v at 200ma on the 5V input; it has on-board regulation.

It is a 3.3v device, but the inputs go through a level-shifter so are also 5v tolerant. The range of the analog outputs is 0-3.3v.

Gameduino 3 is open source hardware and software, released under BSD license. The PCB schematics and layout are here.
