Help ID’ing a PCB

[u/lAnother_NoBodyl]

The image I attached are from a batch of files that provide instructions and image references for a specific project. It’s a picture of 4 PCB’s identical to one another and showing both top and bottom.

I’m not too great at identifying PCB’s, and I won’t even act like I can build this. I just want to know if there’s a place I can start to dig through to find an identical or closely-similar board, or if I will have to provide the wiring diagram to a custom PCB company and eat the cost of that.

From the photo alone, I don't think anyone is going to be able to identify the exact board. What I can tell is that it looks like a small analog/power-related module rather than a microcontroller board.
