Trying to identify a board

Hi all,

I was given a box of sensors and I am trying to figure out what this unlabeled board is. I think its a PIR? but I have no idea.

Here is a photo of the front & back

Thanks!

Closest I’m able to find: https://www.sparkfun.com/products/retired/8663

Yeah, I think that is it. Good find, I was scrubbing the retired page and couldn’t find it.

Well, definitely not what I wanted for this project but glad to know what it is.

Thanks a bunch!
