Okies, so these USB FOBs have a blob of hard (epoxy?) goop on the chip so I can't get at the pins.
BUT, the device has two LEDs and four switches that go direct to the chip.
Why do we need any more I/O than that? Do I even need access to the pins? I should be able to take PTT off one of the LEDs, and put COR onto one of the switches.
Why not? Soldering to pins is the hard way, and lots of devices are potted.
Pin 13 of the CM108 - CM119 is GPIO3, a pin that likely doesn't have a connection to the outside world in a standard BLOB FOB. Same goes with Pin 12. Kevin
