A tiny, RGBW-illuminated, clickable Trackball Breakout that's perfect for adding navigation or control to your Raspberry Pi or Arduino projects.

They've taken a trackball module from everyone's favourite fruit-flavoured phone and added a bunch of clever engineering to let you build old-school interaction into your projects. As well as x/y directional tracking and click, they've added an RGBW (red/green/blue/white) LED right under the clear trackball to illuminate it and allow you to add visual feedback. Use Trackball Breakout with an Arduino that supports USB HID to use it as a tiny mouse.

Because the trackball has a grippy rubber surface you can also use it with the trackball facing downwards and track it as it rolls on a surface, like a traditional roller ball mouse.

Please Note:

  • The trackball breakout only works reliably with I2C speeds up to 250kHz due to limitations in the Raspberry Pi's clock-stretching implementation
  • Mini trackball with click button
  • RGBW LEDs beneath trackball for illumination
  • Moulded plastic trackball casing
  • Mounting Holes
  • Nuvoton N76E003AQ20 MCU
  • I2C interface (address 0x0A/0x0B (cut trace))
  • 3.3V or 5V compatible
  • Reverse polarity protection
  • Compatible with all models of Raspberry Pi, and Arduino
  • Python library
  • Dimensions: 25x22x9.5mm

Kit includes

  • Trackball breakout
  • 1x5 male header
  • 1x5 female right-angle header

Software

They've put together a Python library for Trackball Breakout that makes it simple to read directional values, click events, and set the LED colour. There are a handful of examples of how to read the direction and click, make the LEDs rainbow, and use it as a mouse in Raspbian.
