Name that Ware, October 2025

The Ware for October 2025 is shown below.

Thanks to Juan C. for contributing this curious ware!

I really can’t get enough of how the whole device is integrated with a multi-layer stacked PCB. I imagine that inside the middle of the stack there could be some interesting circuitry going on, too.

I redacted one part number to try and make things a smidge more challenging; at least, an LLM wasn’t able to outright guess the ware when that part number was omitted (but of course, the spirit of the game is to sharpen the wetware sitting on your shoulders by trying to reasoning about the function of the ware, with the aid of reference searches to find datasheets, learn theory, etc).
