When you get it, we can compare pictures of their innards. Mine has a PCB with blue
soldermask. Most of the functionality appears to be in a single QFP, probably with a
central ground/heat slug based on the vias on the bottom side of the board. The top of the
chip appears to have been sanded to remove the markings.
