Can anyone tell me what this is out of?

I don’t know what happened to it or where the rest of it is, I found it on the floor of my house. I am super curious as of to what it is. I have tried to figure it out but failed. Just knowing what it does would even be nice. The wires lead to a USB cable.

I think that's a mouse.

It's a mouse PCB. Can't tell you what mouse though. Most will use a generic board as it really doesn't make any difference, it'll be the sensor that will make a difference mostly.

 

EDIT: Sensor appears to be a an Agilent ADNS-2051, which is essentially a budget sensor so not from a high end mouse.

single sided board so a pretty cheapo mouse

Just a cheapo USB mouse.

 

Looks like the red LED and clear plastic lens are missing.

I was asked to post a picture of the other side. Here it is:

Is there anything fun I can do with it or it is components?

[Simon Hosa]

Funny? Yes there are two electrolytic capacitors 16v they have polarity black is + and white strip is  -  connect them with reversed polarity to about 12v and they will explode. This is something that nobody shouldn't advice to you, especially electrical designers, so if somebody asks you. I didn't tell you anything.  (DO NOT TRY IT WITH MAIN VOLTAGE OR LARGER CAPACITORS)

So it's just a mouse circuit board... the 0502 on the pcb tells you it's from around 2005-2006 ... back then the sensor may have been considered mid-end barely, at 800 dpi... could have been worse.
