In this project we’re building a DIY gamepad using the Bluefruit EZ-Key module and a 3D printed case.

The Bluefruit EZ-Key HID keyboard controller is a bluetooth breakout design for making DIY keyboards and game pads. It’s requires no programing and works with just about any trigger or push button. It takes up to 12 inputs and can be powered with any 3-16 VDC.

The Perma-Proto comes in different sizes which is perfect for making all sorts of projects. The ½ sized Perma-Proto breadboard is like a business card and which makes it perfect for making a small game controller.

Prerequisite Guides

We recommend walking through the guides below - these will help you get familar with the components used in this project.


This is a project that requires a bit of soldering and wiring - It's great for getting practice and well suited for makers with intermediate soldering skills. It's not the easiest 'first-time' beginners project, but it can be done if approached with patience, ambition and positivity. The 3D printing takes 2-3 hours and costs about $1.50 in material. If you don't have access to a 3D printer, check with your local hacker/maker space, library or community collage - they just might have one! Have fun, and happy making!


The parts are available in the Adafruit shop and listed on the right sidebar. Take a moment to look over each components.
