All efforts to get the sensor working have failed, so I'm guessing it's defective. I don't see anything on your site, so...

Hi @jayeff , So I haven't been able to locate a board by the numbers, but it looks like the board itself isn't compatible with older models. I found a prox board for a pixel 7 pro and the board is shaped differently, but the sensor array itself looks identical. It's been 20 years since I've done any SMD soldering, but at least it's a backup plan. What I don't want to do is to open up the device more than needed, so I'd like have a part available in case the actual sensor is defective. They want $18 for the board vs .60 wholesale, but it's an option. I reached out to the seller to see if they could source the proper board, but not holding my breath Thanks for your continued support. Will let you know how it goes.
