Comment on in your household, there is a chip you can easily decap. Can you guess what it is?

If I’m wrong, I’m out of ideas, my house is far from a normal house, so my reference points are wrong.

Congratulations!
Thanks for using the spoiler tag but it’s not working, please follow instructions in the DM I sent you.
The story
My Genius optical mouse was tracking poorly, even on patterned surfaces and mouse mats. I cleaned the lens and that didn’t help. So I opened the chip, which is a pinhole camera with a die that integrates the sensor, a basic image processing system, button, wheel and LED controller and a USB (or maybe also PS/2) interface. I cleaned the chip with alcohol (mainly to remove the dust that had landed on it while it was open) and reassembled the mouse to find that it made no effect on ots functionality. I ultimately found out that the focus distance was off and I fixed it by removing the rubber pads at the bottom. Full picture of the PCB with this chip
