Amazon dash. Anyone hacked it?

Yep! That’s the one I grabbed, and it’s mate: https://www.digikey.com/product-detail/en/panasonic-electric-works/AXE510124/255-3187-1-ND/2793920

But the mounting tabs of that one don’t necessarily fit the PCB above that I got from OSHPark… the pitch looks right though and a little superglue should work for extra stability… or scratch away some soldermask for the mounting tabs.
