Does someone know what kind of circuit board this is?

(Click to zoom)

I found it in an old cardboard box in the basement yesterday. "Sung Wei 08V0-A" is written at the top.

Where can I find schematics, datasheets or technical information about this product?

  • \$\begingroup\$ It's a single layer board, so shouldn't be that hards to trace the circuit. However, I see little point in that. 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. \$\endgroup\$ Apr 9 '13 at 14:24

    \$\begingroup\$ 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. \$\endgroup\$

    \$\begingroup\$ @Madmanguruman They seem OK to me? \$\endgroup\$

Having taken apart a lot of PC mice, I can tell you with confidence that that's a optical PC mouse circuit board. Take a look at all these other mouse PCBs; you can see how similar in construction they all are.

The chip in the middle is an optical sensor. I googled it for its datasheet ("S5008"), but couldn't find any. Instead, some results hinted that the chip is a clone of the Avago ADNS-5000 optical mouse sensor (datasheet here; must be downloaded).

The image of the chip in the datasheet looks exactly like the chip on your circuit board:

As for a schematic, you can have a look at the application circuits in the datasheet of the chip, under Typical applications. That's the closest you can get to the actual schematic of your PCB, unless you do some reverse engineering yourself:
