Azoteq ProxSense I2C Touch Sensor Module / Capacitive Trackpad

A tiny, RGBW-illuminated, clickable Trackball Breakout that's perfect for adding navigation or control to your Keyboard, Raspberry Pi or Arduino projects. We'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, we'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. Or why not use it as a colour/brightness control for an LED matrix breakout or a set of our Mote lights?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.It's compatible with our fancy Breakout Garden HAT (and pHAT), where using breakouts is as easy just popping it into one of the six slots and starting to grow your project, create, and code. Features 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   Kit includes Trackball breakout 1x5 male header 1x5 female right-angle header We've designed this breakout board so that you can solder on the piece of right angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 7, 9). Software We've put together a Python library for Trackball Breakout that makes it simple to read directional values, click events, and set the LED colour. Theres a handful of examples of how to read the direction and click, make the LEDs rainbow, and use it as a mouse in Raspbian. Notes The trackball breakout only works reliably with I2C speeds up to 250kHz due to limitations in the Raspberry Pi's clock-stretching implementation Dimensions: 25x22x9.5mm

To use this trackpad with I2C instead of SPI communication, you have to desolder 2 resistors.Please reade the Guide for more information about it.
