This PMW3360 module can be used to build a mouse or a trackball.

This module can only be used with 3.3V logic level, so DO NOT try to use it with 5V chips (e.g. Arduino AVR) without external circuitry. Modern microcontrollers (ARM, ESP) have 3.3V logic level.

See PWM3360 datasheet for more details about the sensor.

This is a work-in-progress project. It has not been tested yet. ETA: Feb, 2022.
