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. -- Mark J. Blair, NF6X <n...@nf6x.net> http://www.nf6x.net/
