Grove - Mini Track Ball
Grove - Mini Track ball will give an easy access to prototyping a practical motion-tracking function module for your applications. It has implanted 360° detection and click detection with high accuracy and quick response. With chips STM32F103C8T6 and AN48841B inside, you can turn plenty of your ideas into tangible things. It is also standardized with Grove interface which will save you a lot of work in the prototyping process.
- 360° and quick detection.

TipYou can use Grove - Base Shield v2 to make connection work easy.
Refer to the following guides to build an appropriate IDE:
NoteWe have used Seeeduino in this case.
Download sample code¶
1.You can download the sample code.
2.Decompress the downloaded ZIP file.
3.Open the file Grove_-_Mini_Track_ball_test.ino
4.Flash (or upload) your code into Seeeduino board. if uploading process is done, to open Serial Monitor window, Click Serial Monitor under menu Tool.
NoteMake sure you have selected the right Board and Port under the Tool menu.
5.LED indicator under tracking ball will light on in different mode which will last around 50 seconds
6.After that you can rotate or "click" the track ball to get information of its trace.
