Blackberry trackball sensor Mouse trackball Hall effect sensor 360°trackball module<br><br />
<br />
<br />
<br />
<br />
==Regarding LC-EM-1279==<br />
<br />
The trackball module is designed and manufactured using a BlackBerry trackball. The module can drive the X and Y direction axes through the movement of a roller.<br> By rotating the multi-level magnetized magnet fixed on the axis, it sends signals to the corresponding SMD Hall elements to determine the motion trajectory.<br> A small SMD switch is also designed below the trackball for users to trigger events or "click" to select<br />

==Introduction and Explanation==<br />
<br />
'''Board size 20 * 28mm/5g'''<br><br />
<br />

<br />
<br />
<br />
==Functional Features==<br />
<br />
*VCC uses 3.3V or 5V power supply<br><br />
<br />
*The four directions of up, down, left, right, and the button in the middle can be combined for recognition<br />
<br />
*Red, green, blue, and white LED lights can be controlled separately<br />
<br />
<br />
<br />
<br />
==Instructions for use==<br />
<br />
1. Connect to the development board through an 11 pin pin pin. VCC can be 5V or 3.3V<br><br />
<br />
2. Press the middle button on FON, BAK, LEF, left RIG, right SW1. These 5 pins are used as key inputs and connected to the microcontroller<br><br />
<br />
3. RED Red GRE Green BLU Blue WHI White. These 4 pins serve as the output of the microcontroller, with the high-level light off and the low-level light on<br><br />
<br />
4. After connecting, write the program on your own development board<br><br />
