Description
Product information "Trackball Breakout"
We've taken a trackball module from everyone's favourite fruit-flavoured phone and added a bunch of clever tech so you can add old-school interaction to your projects. In addition to the x/y direction and click function, we've added an RGBW LED (red/green/blue/white) right under the translucent trackball to light it up and give you visual feedback.
Use the Trackball Breakout with an Arduino that supports USB HID to use it as a small mouse. Or use it as a colour/brightness controller for an LED matrix breakout or a set of our mote lights?
Since the trackball has a grippy rubber surface, you can also use it with the trackball facing down and track it as it rolls on a surface, like a traditional rolling ball mouse.
It's compatible with our stylish Breakout Garden HAT, where using breakouts is as easy as plugging it into one of the six slots, creating projects and coding.

- 3.3V or 5V compatible
- Reverse polarity protection
- Compatible with all models of Raspberry Pi and Arduino
- Python library
- Trackball breakout
- 1x5 male header
- 1x5 female header right angle
Engineering
There's a remarkable amount of engineering packed into this tiny breakout.
The trackball module itself has a tiny cylinder magnet at each corner, which rotates and is read by one of the four Hall-effect sensors.
Just below the trackball is a tiny dome switch to detect clicks and four LEDs (red, green, blue, white) around the trackball to light it up.
We designed and moulded a plastic housing for the trackball to hold and protect the module in place. This housing can be removed to clean the trackball or roller or to replace the module if necessary.
There is an integrated Nuvoton N76E003AQ20 MCU to read the outputs of the trackball and dome switch, control the LEDs and implement I2C.
Software
We've put together a Python library for Trackball Breakout that makes it easy to read direction values, click events and set the LED colour. There are a handful of examples on how to read the direction and click, make the LEDs rainbow coloured and use it as a mouse in Raspbian.
Hints
- The trackball breakout only works reliably with I2C speeds up to 250kHz due to limitations in the Raspberry Pi's clock implementation
- Dimensions: 25x22x9.5mm

Optimize your Raspberry Pi - with Pimoroni
Pimoni is the expert when it comes to equipping your Raspberry Pi with high-quality add-on modules. The successful company was founded in 2012 in Sheffield, England, and now also has a branch in Essen, Germany. According to the University of Sheffield, Pimoroni is even considered one of the fastest growing manufacturing companies in the UK.
The electronics specialist has the right solution for almost every need around the Raspberry Pi. The product range also includes the Pimoroni Fan Shim, a powerful 30mm CPU fan for the Raspberry Pi, which is one of the top sellers from Pimoroni. The Fan Shim manages a powerful 4,200 RPM and delivers significant added value by optimizing the thermal performance of your Raspberry Pi. Compatibility exists with the Raspberry Pi 4, but also with the 3 B+ and 3 A+ models.
The fan is equipped with RGB LED and a tactile switch, making it wonderfully controllable. The LED serves as an indicator to track the fan status and CPU load/temperature. The tactile switch is also handy: With the help of the included Python library and a daemon, you can program it to switch between temperature-controlled automatic mode and manual mode. Thanks to its "friction-fit" header, the Pimoroni Fan Shim can easily be plugged onto the pins of your mini computer and is ready to go without soldering. In general, the installation is uncomplicated and should not take more than two minutes. While the fan is doing its job, the noise level is very low: The maximum value is only 18.6 dB.
Apart from the Pimoroni Fan Shim, many other top products from Pimoroni are available at Berrybase. The Pibow Coupé 4 is recommended for all owners of a Raspberry Pi 4: The compact case reliably protects your mini computer from external influences like dust or shocks. All ports remain open and thus accessible. The high-quality processed and easy to mount frame for the official 7" Raspberry Pi touchscreen display also fulfills its protective function perfectly. With the Pirate Audio HAT you get a first-class 3W stereo amplifier for your mini computer: Use the module in combination with your Raspberry Pi and your speakers to control the playback of your favorite music and to create powerful sound.
Depending on what you have in mind, you can also use other modules from Pimoroni, such as LED sensors, camera modules or the Pico HAT Hacker.

Eigentlich eine nette Idee, ab...
Eigentlich eine nette Idee, aber die Bewegung der Kugel wird nur bei ziemlich viel Druck (kurz vor dem Auslösen der Tasterfunktion) auch an die internen Achsen der Bewegungssensoren übertragen. Daher werden Bewegungen oft nicht erfasst. Das Maus-Beispiel aus der Arduino-Library hat auch auf einem Pi-Pico sofort funktioniert, die Innenbetriebnahme war zumimdest problemlos, aber aus den genannten Problemen funktioniert es als Mausersatz nur sehr mühsam.
