pcb Help identifying and finding shematics/datasheets for circuit board

The chip in the center with small bullet holes is likely proprietary. It is possible to salvage a few components from it, although understanding the circuit is not necessary for this purpose. Additionally, it is confirmed that the device is an optical PC mouse, and the chip mentioned is an optical sensor.

The optical PC mouse operates using a light-emitting diode (LED) and a photodetector to detect movement across a surface. The proprietary chip serves as the core processing unit, interpreting the signals from the optical sensor and translating them into cursor movement on the computer screen. The optical sensor captures images of the surface at a rapid rate, typically thousands of times per second, allowing for precise tracking of motion.

The LED illuminates the surface beneath the mouse, and the optical sensor detects the light reflected back from the surface. Variations in the reflected light caused by changes in surface texture are processed by the chip, which calculates the direction and speed of the mouse's movement. This information is then sent to the computer, enabling the cursor to move correspondingly.

In terms of components, the optical PC mouse typically includes the following: the LED (often a red or infrared light), the optical sensor (which may be a CMOS or CCD type), the proprietary chip for processing, and various passive components such as resistors and capacitors that help regulate power and signal processing. The design of the circuit is crucial for optimizing the performance of the mouse, ensuring accurate tracking and responsiveness to user input. The integration of these components is often done on a printed circuit board (PCB) that supports the physical layout and electrical connections necessary for the mouse to function effectively.The chip in the middle with the tiny bullet holes in it is almost certainly proprietary. At best you can salvage a few parts if your time is worth nothing, but you don`t need to know the circuit for that. Olin Lathrop Apr 9 `13 at 14:24 Just to make sure: you do know it`s an optical PC mouse, right The chip in the middle that Olin mentioned is an optical sensor.
