While poking around my Pleo I noticed a cover glued just above the power switch.

I removed it, (This most likely will void the warranty so do it at your own risk!) as you can see above the "Old Charging Hole". There is also a 7 pin connector. The first 2 pins, pin one starting from the left, are both ground. The others all have milivolt readings. I am not sure if this is Pleo's JTAG or some sort of serial interface.
